That doesn’t happen with most systems. In fact, there are only three camera ecosystems that really pull me back in when I’m without them — OM System, Fujifilm, and Nikon.

So why is it, with a world of larger sensors and technically “better” image quality, that the smaller Micro Four Thirds format keeps drawing me back? Why did I recently buy the OM Systems OM-3? and how does it feature so highly on my recent article on the best cameras for family photography.

Ergonomics That Just Feel Right

For me, ergonomics are everything. In an age where nearly every camera from the last five years is “good enough” in terms of image quality, how a camera feels in my hands becomes incredibly important.

Olympus — and now OM System — simply nailed this. The OM/EM bodies feel like an extension of myself. Compare that to when I tried the Nikon Zf last year: technically brilliant, but the ergonomics never clicked, so I couldn’t connect with it.

When a camera doesn’t inspire me to pick it up, all the specs in the world don’t matter.

More Than Just Small and Light

People often assume the appeal of Micro Four Thirds is only about weight. But that’s not the whole story.

The OM-1, for example, isn’t really much smaller than my Nikon Z6 III and is actually heavier than my Fujifilm X-T5. Yet I still reach for it. Why? Because it’s about confidence, not grams. These cameras feel solid, dependable, and built for anything. So when the weather turns, I’m going off the beaten track, or I want to minimise the accessories I need, they’re my go to cameras.

Packed With Features Others Can’t Match

This is where Micro Four Thirds really shines. OM System cameras come loaded with features that make photography easier and more creative:

• World-class IBIS — still the best I’ve used.
• Live View / Live Bulb / Live Composite — long exposures made simple.
• Handheld High Res — 50MP files with better color and noise than the base sensor.
• Built-in ND and graduated ND filters — leave the tripod and filter kit at home.
• Pre-Capture for Wildlife — with the OM-1, this feature has made my life so much easier when photographing birds or fast action. It records frames before you fully press the shutter, meaning you don’t miss the decisive moment. Nikon thought it was so good they built their own version into the Z9 and Z8.

With my OM-3, I can shoot handheld one-second exposures, create high-res files, and even pull off long exposures without a single accessory. That’s freedom other systems just don’t give you.

A Lens Lineup That Makes Sense

The Micro Four Thirds lens ecosystem remains one of the most complete out there.

Yes, other systems have caught up with smaller primes, but MFT still offers a mix of compact, high-quality lenses that cover every focal length. And while people argue endlessly about depth of field equivalence, the reality is simple: f/2.8 is f/2.8.

An f/2.8 zoom on Micro Four Thirds gives me fast shutter speeds, excellent build quality, and optical performance that often surpasses budget f/5.6 full-frame zooms.

Proven Legacy of Innovation

Micro Four Thirds has always been a pioneer:

• Olympus/OM led the way with the best in-body stabilization for years and still does, it’s still the only main manufacturer that gives an actual rating for its weather sealing, and those groundbreaking live exposure modes still haven’t been matched by others.
• Panasonic pushed video forward with the GH line, changing what was possible for hybrid shooters.

Many features we now take for granted in full frame or APS-C cameras started right here.

Not Perfect — But Worth Preserving

I’m not saying Micro Four Thirds is the best system, or that everyone should shoot it. It has limitations, and the sale of Olympus’ imaging division raised real questions about the future.

But I’d argue it still deserves its place. Not out of brand loyalty, but because the more viable systems we have, the better it is for photographers. Choice breeds competition, and competition creates better cameras for all of us.

Some online voices want to write Micro Four Thirds off as “dead.” But why would anyone wish for less choice? I wouldn’t want Sony, Canon, Nikon, or Fujifilm to vanish either. Each system offers something unique, and sometimes the one that gets written off turns out to be the one you miss the most.

For me, Micro Four Thirds still matters in 2025 — not because it’s perfect, but because it makes me want to go out and shoot. And in the end, that’s what really counts.

Firstly let me say that all the specs are available online so I’m not going to go through them all here. I’ll just talk about those that mattered to me for the project that I have planned. Those being image quality, AF, handling and performance.

While the GX9 and EM5 III uses a 20mp Micro 43 sensor the Fuji XT30 makes use of the larger 26mp APS-C sensor found in the XT3 so it should be a no brainer that the image coming out of the Fuji is better and it performs better when pushing your ISO higher. The thing is that when reading forums on the internet they would lead you to believe that the difference is night and day and this simply is not the case. Yes the Fuji is slightly better once you get up to 3200+ ISO but the differences wont be enough to make or break an image. For me the more interesting question was about the colour each camera produced and I was particularly interested in the Acros black and white profile of the XT30 as a lot of my project will be shot in black and white. Quite frankly I chose the XT30 as one of the most affordable ways to get the Acros profile.  In my opinion the image quality produced by all the cameras is good enough for what I had in mind.

Fuji are heralded within the media for being excellent for portraits, skin tones and the Acros profile and in a lot of situations I know why. I love the organic look of the colours coming off the X-Trans sensor and under the right lighting conditions the Acros profile produces some beautiful black and white images. However sometimes the colours can feel just a little flat while the Panasonic and Olympus in my opinion actually produce more pleasing colours more of the time. I am a big fan of the colours that both Panasonic and Olympus cameras put out SOOC. For me they win when shooting colour images but the Fuji does well for black and white work. This is why I bought an XT 30 just for this project. However I like the Fuji and Panasonic black and white rendering equally and it really depends upon the subject and light as to which is better in a given situation.

In terms of handling all the cameras are small, lightweight and discreet. They are quick in use and it is easy to quickly change settings on them. I prefer that the Olympus has a separate door for memory cards and I still prefer the PASM system employed by virtually every camera manufacturer rather than the separate dials for shutter speed employed by Fuji. (note the XT30 has a shutter speed dial which when using most Fuji lenses combines with the Aperture ring to give control over exposure). The XT30 does not have and ISO dial unlike its big brother the XT3.

All the cameras feel well built although I’d have to give the nod to the GX9 and Em5III (although I have heard issues reported around the strength of the tripod plate on the EM5II) as they just feel a little higher quality finish and of course the Em5III is weather sealed.

I had fully expected to love the little Fuji XT30 but there were 2 major issues for me once I had a little time with the camera. Firstly, I wanted to shoot the 35mm 1.4 and 56mm 1.2 for my project and quite frankly the AF motors on these lenses still proved to be pretty poor. I had hoped that with the latest generation of camera bodies the AF when using these lenses would have improved but unfortunately (and this is no fault of the XT30’s) it hasn’t. Now I know that a lot of Fuji users love these lenses and in terms of their image quality, yes they are gems but the problem I had while testing the gear out (on not very trying subjects) was that it took multiple shot to get perfect focus. No, it wasn’t a bad copy of the lens, this is exactly how I remember my previous version being as well. I guess it is my own fault for hoping for an improvement that simply can’t be provided by a newer camera. These lenses desperately need updating and I really hope Fuji is working on this as their more modern lenses perform much faster. However it is these lenses that I particularly wanted to use. I’m not interested in the f/2 primes as I’m giving up some of the benefits of that APS-C sensor when shooting with them. In all honesty I like the ergonomics and handling of the EM5 III the most, so unless the XT30 is going to give me tangible benefits (which it would if these lenses auto focussed quickly enough) over it then I’m not going to choose it. The EM5 III is simply more fun and gives me more confidence that I can nail the focus every time.

While the Fuji XT-30 does offer slightly improved High ISO performance the differences are minimal and I’d still place my limit of acceptable IQ for portraits at ISO 3200, exactly the same as the Micro 43 cameras.

The second major issue (and one which even had me and my wife spend and evening trying to figure out) was the Fuji App to transfer images to your mobile device. I have used this app before, along with the ones form every other major camera manufacturer (except Canon). The best ones are from Olympus and Panasonic, Sony’s is fine too and Nikon’s although temperamental usually works. Well this Fuji App is a complete and utter bag of S**t. I spent hours trying to get it to connect to my phone, my wifes phone, my tablet and in the end gave up. When I’m out in the middle of nowhere taking photos and I want to quickly transfer some images then this is a big no no for Fuji. I didn’t previously have this issue when I owned the XT2 so I can only assume that the updated app is either useless, has compatibility issues or it’s the XT30’s fault. Either way in the end no matter how beautiful the Acros black and white images were, far too many were out of focus and when they were in focus the app made viewing them on my mobile device impossible. The Fuji is sadly out of the race and has been sent back.. As you saw in my Olympus OMD EM5 III Review this camera does everything that 90% of people will need it to do with no fuss. It makes photography easy and fun and dare I say it, quite cool too.

However I already own the Panasonic GX9 and a GH5 so is the Olympus at approximatley £1000 twice as good as the Panasonic GX9 which can be had for under £500 (as of early 2020)?

In the Olympus’ favour it has slightly better IBIS, is weather sealed, has a better viewfinder and offers Hi Res mode as well as the useful long exposure modes such as Live Bulb and Live view. In the Panasonic’s favour for me is the fact that it uses the same menu system and has the same colour profile as my existing GH5 and so using the two together would be a more seemless experience and mean my lazy ass doesn’t have to memorise two menu systems. It is of course half the price.

When I wrote my Olympus EM5III review it was before the Coronoavirus Pandemic had really hit the UK hard. Money and business was quite good and I could afford the additional cost of the EM5III over the GX9. However as I sit here writing this (early April) the UK economy has basically shut down, business has dried up and I am now putting a much higher priority on bang for buck to ensure that I get the most out of any investment that I make in to a camera or system. This puts cost way higher up my list of priorities than would previously have been the case and I’m sure like many photographers out there I am now really asking myself the question, do I honestly need these extra features and are they really going to make a difference to my work and earning potential.

For me, in the end it comes down to the image I can produce. Yes it is nice to have the better viewfinder but the one in the GX9 does not hinder me from getting the shot. I also quite like the tilt mechanism on it. Yes, hi res mode would be nice to have and I can see myself using it quite a lot for landscapes but the projects that I have lined up will be fine with 20mp of resolution. Am I going to suddenly start doing a lot of long exposure photography to make use of live bulb and live view…..If I’m bluntly honest with myself then no, that just isn’t going to happen.

Does my camera need to be weather sealed? Well a lot of us like to kid ourselves that a certain specification is an absolute must. I hear people all the time saying that weather sealing is absolutely essential. I don’t buy it for the most part. I used to live in the Outer hebrides, a place where the weather could not be more challenging to a photographer. My cameras back then didn’t offer top notch weather sealing and you know what I did when the heavens opened… I popped my camera back in my camera bag and waited for the torrential wind blasted downpour to pass. Just before and just after the storm is the best time to photograph anyway not during it. Even if the cameras were weather sealed like a tank the front element of the lens woud be covered in rain and ruin any image. The philippinnes, just like the Outer Hebrides is prone to sudden torrential downpours but for the subjects that I plan on shooting it is irrelevant as I doubt many portrait subjects will be willing to stand out in the rain while I photograph them. Long story short, weather sealing is nice to have but not essential for me.

Both the GX9 and EM5 III have fast enough AF speed for my needs. Yes the Olympus may be a little better at tracking thanks to its phase detect Af points but it doesn’t make a difference for what I shoot as the GX9 is quick to focus and has decent face and eye detect AF.

Conclusion

The crux of the matter comes down to which camera offers the features that I need in the cheapest package and this is where the GX9 delivers in spades. IMO it is probably the best value camera in the photographic universe at the moment.

In terms of output it is virtually identical to the Olympus EM5 III however it actually bests it in my opinion in one area that is vital to my project. The black and white profiles of the latest generation of Panasonic cameras and in particular L Monochrome D is just about my favourite black and white profile of any camera.

Despite wanting the Fuji XT30’s black and white output the |fuji sytem currently has too many compromises to work for me (Slow AF, No IBIS, Poor Wifi App, No PASM). Despite quite liking a lot of the EM5III features I don’t really need them. My Panasonic GX9 takes beautiful black and white images (particularly in the L Mono and L Mono D profile) and offers everything that I need in a small lightweight package. It doesn’t hurt that it looks beautiful too. So I’ll be using it alongside my GH5 for my projects this year.

Update: June 2025 – I have since bought and extensively used both the OM Systems OM1 and OM1 Mark II which are both fantastic cameras. I’m also now testing the OM3 and explained why I bought it here.

Today I am going to share my Olympus OMD EM5 III review with you.

I have been waiting for what seems like an age for the release of the Olympus OMD EM5 mark III camera. As an avid Olympus user over the years I have been fortunate enough to try out all of their top tier cameras since the original EM5 right through to the EM1X. I used the EM5 II as my main camera for around a year and you can see my review of that here 

The OM5 and OM5 Mark II have both been released since this review but the performance of both of those cameras remain very similar so I believe this review is still valid, even if you are looking at the more recent models. 

Yet somehow while I was caught up in our recent house move from the Philippines to the UK I missed the official release. It was only when I got back to the UK and had time to settle that I picked up that the third iteration of the Olympus EM5 had been announced, released and was on sale. The orignal EM5 was the camera that lured me away from shooting DSLR’s for my professional work way back in 2012. The competition has come a long way since then with Sony flooding the market with 35mm sensor sized options and Fuji providing attractive APS-C options.

I had high hopes that the OMD EM5 III would bring together everything I love about mirrorless cameras, small form factor, beautiful design, advanced features. ease of shooting and hopefully, an upgraded sensor.

On reading the specs there are two ways to look at it… We didn’t get a brand new sensor from Olympus as some had hoped but we did get the excellent one out of the EM1 II. This along with phase detect auto focus, improved image stabilisation, OLED viewfinder, 4k video and that beautiful form factor and design was enough to have me clicking the buy now button and ordering one to test.

For this Olympus OMD EM5 III review I have purchased the camera myself and will be using it in depth to see if the EM5 III is worth the money and can compete in todays even more competitive market place.

Olympus OMD EM5 III Review – Handling

The Olympus EM5 and mark II had a metal construction which gave them a really substantial feel in the hand. Yes they were tiny but they felt well built and easily capable of surviving the daily scrapes our gear sometimes has to deal with. The new Olympus EM5 III has dropped the metal construction in favour of a lighter poly-carbonite shell. I must admit this had me a little concerned when I first read it as I wondered if they had shifted the EM5 series further down their product lineup and were aiming it at a different, less demanding audience.

Well in all honesty I prefer the feel of the mark III over my original and mark II versions. It feels noticeably lighter at 414g down from the mark II at 469g. It also feels a little smaller but it is actually more comfortable to hold thanks to a thumb rest that protrudes more from the back of the body. This allows for great purchase on the camera and I have no issues with the balance of the camera when combined with larger Olympus lenses like the 12-40mm Pro. There is an optional grip which would be welcome if using the pro telephoto lenses although I note that a full battery grip is no longer going to be offered as an optional accessory. I presume because Olympus wants you to purchase an EM1 series body if you require this functionality. I can understand that and although I would like the option of a battery grip I, like most other buyers probably value the light weight and compact nature of the EM5 bodies more.

When I did my Olympus OMD EM5 III unboxing video I was so interested in the feel of the camera that I didn’t even initially notice some standout changes that Olympus has made to the body of this EM5 III. I’ll go over these now in this Olympus EM5 III review.

Firstly, the control dial is now on the right hand side freeing up space for dedicated buttons to select the shutter mode (single, burst, Timer etc) and another that by default switches the LCD display from showing a live display or the Olympus Super Control panel. Damn, no single handed switching the camera on then.. A quick play around in the menus and I found my trusty option to use the function lever to turn the camera on and off, problem solved.

Another addition that I’m happy to see is a dedicated ISO button just to the right of the thumb rest. It’s not ideally position with my thumb (at least) having to stretch slightly to reach it but it works and its there, so again I’m pretty happy.

For any existing Olympus users the handling will be very familiar and now more in line with that found on the EM1 series bodies which will offer better continuity when switching between bodies. I can envisage people (myself included) using the EM5 III when they want to be lightweight and discreet (think street photography, candid portraits, family outings, long treks etc) and the EM1 series body with larger lenses for more serious work.

The Olympus EM5 III still has a 3 inch fully articulating screen (unchanged from the previous model) and it does its job more than adequately for my needs. Yes there are larger screens with more resolution available but is it really needed? In my eyes not really. Yes, more is often a good thing but this screen shows me the information I need quickly and clearly.

One change on the EM5 III that I do really appreciate is the new 2.36 million dot EVF. Although the magnification has decreased slightly (0.69x ) it is a vast improvement over the old model and provides a clear rich image. Yes higher resolution EVF’s are available on more expensive models from other brands but while these are nice I honestly don’t see them as essential as long as they are good enough to clearly frame your shots. One thing to note for those among us that wear glasses is the 27mm eye point.

Overall the handling of the Olympus OMD EM5 Mark 3 is almost exactly what I want in a small mirrorless body. Its buttons offer good tactile feedback (no more squidgy buttons here) and the front and rear control dials are the best in the business offering just the right amount of resistance to feel solid and assured in use.

Video

I now do quite a lot of video both in my work and for my Youtube channels and I’m pleased to see that Olympus kept the mic input on the EM5 III. This along with the ability to record in 4K at 24 and 30 FPS, as well as 120 FPS in 1080 make it a pretty good option for casual video.

Having looked at the video quality produced by the EM5 III I would be quite happy using it for my Youtube channels. Combined with the excellent IBIS as well as vastly improved video AF I found it easy to get good results straight out of camera.

The colours are beautiful as I would expect from Olympus and I believe it would be more than capable of putting together very nice looking travel videos and vlogs, aided by that fully articulating screen.

I currently use a GH5 for video work which as we all know has a plethora of options but for less demanding users I believe the EM5 III will be more than good enough in terms of output quality, colour and usability as long as you don’t need 4k60 which is sadly missing.

The only issue I would mention is that the headline bit rate of 237mbps is only available for cinema 4k (including fast motion up to 8x speed) and then drops down to 102mbps for 4k at 24,25 and 30 FPS.

If slow motion is your thing the EM5 III can shoot at up to 120FPS in 1080 but the bit rates drop off significantly from the numbers above which could cause quality issues, particularly if you may grade the footage. The 120 FPS high speed option shot and re-timed in camera only offers 26 MBPS.

The highest bit rate when shooting in IPB is 52 MBPS for 1080 , regardless whether the frame rate is 24, 25, 30, 50 or 60. You can shoot 24, 25 and 30 FPS footage in All Intra at 102Mbps.

Sample video will be available once I upload my Video review to Youtube.

Auto focus

Olympus have put the sensor (including Phase detection AF) from the EM1 II into the EM5 III and it really does show. Now let me just clarify one thing, I am not a sports shooter. I hate firing away like a madman in the hope that if I spray enough bullets I’ll hit the target. Not to mention I don’t have the will to go through thousands of pictures just to find the one good one. So I have not tested the EM5 III AF for sports or birds in flight which are arguably the most demanding tasks for an auto focus system.

However I have shot a variety of subjects from portraits to my 3 year old daughter tearing around on her bike.

Single AF, S-AF in Olympus’ language is as fast as the fastest cameras out there. If you can’t get in focus shots with this camera then I’m afraid it’s not me, it’s you says the EM5 III. The focus is snappy, assured and never skips a beat. That’s to be expected these days although some do better than others and of the cameras I have used Olympus is easily up there with the best for single AF.

The interesting thing with the EM5 III is that it now has phase detect AF for the first time so in theory its continuous AF and tracking modes should be vastly improved over its predecessor. In short yes they are.

Shooting multiple portraits of my wife using eye AF and C-AF the camera locks on to her face and eyes and nails the focus almost every time. It is also doing a better job of following the subjects face even when they are not face on to the camera.

I also tested out the tracking AF using my daughter riding her push bike. The results were pretty impressive, especially when compared with previous generations of the EM5.

With the subject riding straight towards me at a jogging pace the camera picked up focus immediately and followed her through until she filled the frame and exited to the side. The last couple of images were out of focus but 80% of the remaining series were all perfectly sharp with 15% being acceptably so and just 5% being unusable.

When tracking a subject across the screen the results are better still. In fact they were all perfectly sharp.

So for normal use photographing people, kids, pets, the Olympus EM5 III is more than up to the job in terms of AF. The only issue and one I would like to see improved in a firmware update is that when several faces are in the scene I couldn’t find a way to select which face to focus on. The AF is also very usable for video and certainly better than my GH5.

Olympus OMD EM5 III Review – Image Quality

I will add a few test shots below for those of you who want to compare ISO in a more controlled manner but for the most part I find that the biggest test for a sensor in terms of high ISO performance is capturing skin tones. The smooth skin of a models face really does show up issues when using higher ISO’s and this is something that the EM5 II had started to fall significantly behind with compared to the competition.

Of course a Micro 43 sensor does have an inherent disadvantage in low light performance due to its smaller size compared with APS-C and 35mm. However whenever I have tested this I am always surprised just how close to APS-C it gets. Don’t get me wrong if you want and need killer low light performance then you need a larger sensor but I am yet to produce an image at ISO 3200 or above on any camera which I would consider a true keeper. If an image is that important then I am generally shooting at lower ISO or controlling the light. I understand that some people (documentary photographers, nightlife and wedding photographers etc) do genuinely need the best possible high ISO performance but for the rest of us, is a very usable ISO 6400 not enough? If it is dark enough to need ISO 12800 or more then I honestly doubt the image is going to be that good anyway. I know I will get some angry responses and justifications to that last comment but for how and what I want to shoot I rarely go above ISO 1600 and if it’s a landscape I’m at base ISO anyway.

With that said I am pretty happy with the high ISO performance of the Olympus OMD EM5 III. ISO 3200 is very good and 6400 looks very usable too. I would even say it is a little better than my EM1 II at high ISO as the 12800 shot below doesn’t fall apart as badly on the EM5 III as it has on my previous Olympus cameras. The magenta cast that the EM1 II sometimes suffered with at high ISO’s is also no longer present on the EM5 III. Below I shot an image in near darkness as I prefer to test ISO performance like this rather than shooting in daylight and raising the ISO for the sake of it.

To be perfectly honest, this is the first time I have been totally happy with ISO 6400 on the Micro 43 platform. I always thought it was usable with a bit of work in post production but with the Olympus EM5 III it has now edged over into perfectly satisfactory and ISO 3200 looks very clean. Of course when shooting with the EM5 III you’re only going to need to use those higher ISO values if you need to use a faster shutter speed to stop action. Otherwise you can hand hold this camera in almost any situation thanks to the incredible in body  image stabilisation. All the test shots above were shot handheld with the 45mm Pro lens. The ISO 200 shot used a shutter speed of 1 second and was almost perfectly sharp. That would usually require a shutter speed of 1/100th to be sharp. That’s over 6 stops of image stabilisation working right there and to be honest I didn’t bother about my technique, I have so much faith in Olympus’ IBIS that I just fired away without really thinking about it. It is unlike any other IBIS system I have ever used and yes I have owned the Panasonic G9 but the EM5 III, EM1X and the EM1 II are all much better in my opinion. I know some test results put them close but that was not my personal experience.

So if people say that you need a large sensor to shoot in low light I would say it depends entirely upon what you are shooting. Yes there are scenarios where the larger sensor will be of benefit if you are shooting moving subjects and need to freeze the action but for anything else the EM5 III can shoot at ISO 200 and give you great results.

One thing I had noticed on the EM1 II and previous Olympus bodies that I have owned (so most of the higher end ones) is that the red channel was prone to becoming over saturated and clipping. I can say that this issue seems to have been resolved on the EM5 III.

This is especially true if you shoot in Raw rather than JPEG as the raw files hold substantially more detail and information as you can see below.

If you want to see all the full resolution images from this review then they are all available over on my Flickr page.

As you can see from the above image the raw files are holding substantially more detail and colour information. When I zoom in 100% on the Jpeg file here I can just see a few areas where the red channel is starting to clip slightly. However there are no such issues in the raw file. The raw file also shows more fine detail such as the veins of the petals which are not visible in the Jpeg. It should be noted that I turned in camera noise reduction down to the minimum setting but it can also be turned off altogether.

High resolution mode

The Olympus EM5 III now gives us 80mp raw files and 50mp Jpegs in high resolution mode thanks to the new 20mp sensor inside the camera.

At first glance the hi res shots show a noticeable improvement in detail but is this simply due to the larger file size?

I wanted to see how they compared with a standard raw file that was up-rezzed on my PC to match the file size of the in camera hi resolution image.

The in camera hi resolution image contains more genuine detail than the standard raw file up rezzed to match. The other main benefit that is quite obvious is that the in camera hi resolution image is giving a noise benefit too. Olympus themselves claim 2 stops improvement when using the high resolution mode. I believe this to be pretty accurate. The file is cleaner and contains more detail so if you really want to get the best output possible then it is worth using the high resolution mode. Just make sure that you take the time to ensure you are using the camera on a rock steady tripod and use a shutter delay. My first attempt to capture this hi res image resulted in softness caused by the vibrations when I pressed the shutter release. A delay of 8 seconds was sufficient to get perfectly sharp images.

I still have to test the hi resolution mode for landscapes to see if it deals with movement any better than previous generations. I’ll report back once I have thoroughly tested it.

Olympus OMD EM5 Mark 3 – Conclusion

The Olympus OMD EM5 III has been a long time coming so was it worth the wait? On the one hand if you look at the technical specifications and price some may argue that there are no standout features in such a competitive marketplace. However it is only when you actually get the camera in your hands and use it that you can appreciate all the little improvements that in the end add up to one of the best handling and performing mirror-less cameras on the market. Let’s not forget that Olympus’ IBIS is definitely still the best available.

The build quality still feels reassuringly good, the new thumb rest gives just that little more purchase to make it more comfortable to shoot with. The new EVF is crisp and clear and little additions such as the dedicated ISO button improve the handling to the point that this camera simply gets out of your way and lets you shoot. For me this is more important than an extra stop of dynamic range, a few more megapixels and being able to fire off a million shots a second. That is just the way I prefer to shoot though. I prioritise the experience when using a camera as long as it is able to give me the end results that I need.

In the last year I have heard quite a few people predicting the demise of Micro 43 and in particular Olympus, citing Sony’s A7 line as being far superior. I don’t deny that the Sony A7 series are great cameras, I have owned the A7R, A7II, A7R2, A7III and A7rIII.

While the Sony A7 series bodies are in the same size and weight bracket as the higher end Micro 43 offerings like the EM1 II and GH5 the professional grade lenses are no smaller than those on full frame DSLR’s. Yes they will get you better low light performance and more megapixels to play with and if you genuinely need those things then no doubt you will already know so.

However for the rest of us who want a fast responsive camera with good AF, a big step up in image quality from your phone, more features than pretty much any other camera on the market and a range of high quality lenses from super wide angle to super telephoto then I think the EM5 III offers that. All wrapped up in a lightweight package that you will be much more likely to carry than a bulky DSLR.. I know that I will take my Micro 43 cameras out with me on trips where I would leave the Sony cameras behind and in the end as the cliche goes, it’s the camera that you have with you that’s the best.

I get to try out a lot of cameras and I usually know which ones I would be happy to keep pretty quickly. For me the Olympus OM-D E-M5 III ticks all the boxes for what I want in a camera and I’ll be keeping mine for some time to come. In future articles on this website and videos on my Youtube channel I will be putting the EM5 III up against my Panasonic GX9 and a Fuji XT30 so be sure to check back soon for those comparisons. I’m also hoping to pick up the recently announced EM1 III and Fuji XT4 to compare those two models.

I’ll be updating this page from time to time when I have more sample images and hopefully get a chance to shoot some proper landscapes (if I ever get the time) over the coming months. I hope this Olympus OMD EM5 III review has been useful for you. Now get out and shoot.

I just took delivery of a Sony A7R II yesterday with the Zeiss 55mm f/1.8 lens. Part of my decision to buy this combination was to supplement my Olympus OMD EM1 II with a camera with a full frame sensor as I believe Micro 4/3 and full frame compliment each other as systems very well. The idea being that the Olympus will be my everyday camera and the Sony will allow me to get more subject isolation and better low light performance when I need it.

The difference between micro 4/3 and APS-C is so negligible that I don’t see the benefit of owning both for my uses.

Anyway I thought it would be interesting to do a quick test to see the difference between the two when it comes to subject separation.

I shot both on a tripod from the exact same location. The Zeiss is a 55mm lens whereas the Olympus equates to roughly 50mm so the field of view is not exactly the same with the Zeiss being a bit narrower. The Sony was paired with the Zeiss 55mm f/1.8 and the Olympus with the 25mm f/1.2 Pro (see my review here ).

So here are both shots wide open.

The Sony is definitely doing a better job of isolating the subject and that is no surprise as the 25mm 1.2 on the Olympus is roughly equivalent to a 50mm f/2.4 on full frame in terms of depth of field and field of view. Part of the difference can be put down to the longer focal length of the Zeiss lens but even then here are the things to look at that highlight the differences.

Look at the detail in the brown unit to the left of the top of the lens. The Olympus is picking up more texture and details whereas the Sony has blown most of that into smooth out of focus rendering.

Secondly the light sphere immediately left of the focus markings on the lens is much more in focus on the Olympus shot than the Sony one.

So even wide open and with a larger aperture the Olympus 25mm 1.2 can’t quite match the Sony with a 1.8 lens.

Here are  the Olympus and Sony both at f/1.8 side by side in Lightroom so you can directly compare like for like what you would get when shooting at the same apertures on different systems.

So as you can see the Sony definitely offers an advantage when you want to isolate your subject. Just as expected. You can of course also buy lenses with a larger aperture for the Sony system which will widen the gap further. However I have no intention of buying those lenses, not because of the price (which is expensive) but because I don’t want to imbalance the camera by putting on huge lenses that will make the whole setup incredibly front heavy.

So if you want that creamy shallow depth of field look then it’s a no brainer right? Get full frame….. Or is it.

One thing to note is that these Olympus Pro line of lenses have a trick up their sleeve that can level the playing field somewhat if you are not constrained in your shooting position.

They can focus incredibly closely.

All the shots above are taken from the closest focusing distance of the Sony Zeiss 55mm 1.8. In these circumstances the full frame Sony clearly does better. However take a look below at just how close the Olympus 25mm 1.2 Pro can focus. The lens hood was nearly touching the subject when I too this.

I’m not arguing that one is better than the other here. For some things the Sony will be better and for others the Olympus. That is why I bought the Sony A7Rii to compliment, not replace my Olympus OMD EM1 ii. For example when I shoot the Olympus 25mm 1.2 Pro I get the light gathering of a 1.2 lens but I gain a little extra depth of field which can be useful to ensure enough of your subject is in focus. More depth of field can be an advantage at times.

The Sony will of course give me better low light performance, a little more dynamic range and the ability to print gallery sized prints with more detail but if anyone tells you that Micro 4/3 is not capable of producing shallow depth of field images then you can safely ignore them as they clearly haven’t used lenses like the 25mm 1.2(review here ), 45mm 1.2 (review coming soon) and 75mm 1.8 (review here )from Olympus.

Update: OM System 25mm f/1.8 Mark II now available

OM System has recently released the updated 25mm f/1.8 Mark II, and it finally adds weather sealing — one of the biggest omissions from the original version reviewed here. I have also recently reviewed the 17mm 1.8 mark II lens. Optically, it appears to be identical, but the added sealing and refreshed exterior design make it a more future-proof choice for OM-1 or OM-3 users who shoot in unpredictable conditions. I’m using it regularly on my OM Systems OM-3 and used it in my comparison of the OM-3 and Fuji X100VI. In fact this lens and the other 1.8 primes are part of why I love using my OM-3.

I’ll be testing the new version soon along with the O-M3 and will update this article with a full comparison. In the meantime, if you’re torn between the original, the new Mark II, or the f/1.2 PRO, check out my OM-1 review to see which lenses I use most often in the real world.

The Olympus 25mm f/1.8 is a premium fast aperture prime lens from Olympus. It is available in either silver or black. I have the black version and have been using it on my OMD EM1 ii.

Olympus 25mm 1.8 Review – Construction and Handling

The Olympus 25mm f1.8 is constructed using high quality plastics. It feels nicely built and not cheap like Canon’s nifty 50 lens. The lens makes for a very light and compact combination even on Olympus’ larger bodes such as the OMD EM1 ii.

I have been out this morning for a Sunday stroll with this combination and it feels so light and compact that I hardly even noticed that I was carrying the camera.

Thankfully Olympus supply this lens with a lens hood although I haven’t used it much but it is certainly right and nice that Olympus saw fit to include a lens hood with this lens.

In terms of construction it feels more solid and better made than the cheaper kit zooms but it is not up to the standards of the Olympus 75mm 1.8 or the pro grade lenses but then this lens is not in the same price category coming in at under £300 on Amazon UK.

Autofocus performance of this lens is nothing short of excellent. It is incredibly quick to focus and silent too. It focuses instantaneously and is very accurate. Whether the scene is front lit, back-lit or when using it in low light the auto focus performance is a s good as any lens in the system. It is noticeably quicker to focus than the Panasonic 25mm 1.4 for instance and as quick as the Olympus 25mm 1.2 Pro. Both of which are more expensive.

Olympus 25mm 1.8 Review – Image Quality

The Olympus 25mm 1.8 doesn’t suffer from any noticeable distortion. It is also highly resistant to lens flare, even when pointing it directly at the Sun as I did this morning.

It doesn’t suffer with CA in high contrast situations and in fact having tested it over and over again I am very impressed with the performance of this lens in every aspect.

The lens also focuses incredibly closely at 25cm. Combine this with the f/1.8 aperture and you ave the ability to really throw the background out of focus to create some nice bokeh effects.

The lens is sharp wide open and doesn’t really show much improvement when stopped down further. Again the performance of this lens is excellent.

Olympus 25mm 1.8 Review – Conclusion

Unfortunately, my version of the Panasonic 25mm f/1.4 broke — it simply stopped working one day and never powered on again. It seems the internal electronics or contacts failed after just a few months of use. This was actually my second copy of the lens, and I didn’t have this issue with the first, but it’s still a little concerning and has put me off the lens, which is a real shame. The rendering is beautiful, and in terms of size, it strikes a lovely balance — sitting right between the OM System 25mm f/1.8 and the 25mm f/1.2 PRO.

There are now a lot of choices in the Micro 4/3 system for this focal length. I currently have 3 25mm lenses, the Pana-Leica 25mm 1.4, Olympus 25mm 1.2 Pro and this lens. So which one should you choose?

The performance of all 3 lenses is stellar, however the price points vary so is it worth paying more for the other the lenses.

In terms of optical performance they are all excellent. Only the Panasonic lens suffering slightly with CA. All are sharp wide open. The Olympus 25mm 1.8 is the cheapest option and if you have an Olympus camera I would recommend it if you don’t need weather-sealing and the 1.8 aperture is sufficient for your needs. It is also the lightest of the 3 lenses and makes a great walk around package even with my OMD EM1 ii. It is also small enough to carry in a pocket and light enough to sling in your camera bag as a just in case you need it lens.

Of the 3 lenses I would say it offers the best price/performance ratio and is the one I would recommend to most people. It really is a fantastic little lens and its performance is so close to the 25mm 1.2 optically that unless you really need f/1.2 or weather-sealing then it is hard to justify the additional cost of the Pro lens.

On an Olympus camera I also prefer the handling and auto focus performance to the Pana Leica 1.4.

I’ve used it with my OM-1 and OM-1 Mark II to make some of my favorite portraits of my daughter Sofia — who is now (unbelievably) 9 years old. One of the photos from the original review shows her as a toddler. The black and white photo below, taken just recently in the snow, shows her smiling all these years later.. Same lens. Same joy. That’s the kind of relationship you build with gear that truly lasts. I’m taking the 25mm 1.2 along with the OM3 on a trip tomorrow. It’s still one of my favourite lenses for any system. In fact that’s why I just featured it in my best lenses for travel photography article.

In this Olympus 25mm 1.2 Pro review I shall go through the pros and cons of this premium lens from Olympus and weigh up whether it is worth the extra cost over other 25mm options like the Olympus 25mm 1.8 and Pana Leica 25mm 1.4 lens.

Back to the Review

I have had this lens for a couple of months now and mainly used it in Asia for portrait and travel photos on the Olympus OMD EM1 Mark ii and Panasonic GH5. If you want to see how those two cameras compare for stills photography then head on over to my comparison here

Olympus 25mm 1.2 Pro review – Specs and handling

Obviously the stand out specs for this lens are the super fast 1.2 aperture along with the weather sealing.

The lens feels very well made, the same as all Olympus’ pro lenses. It is quite large by Micro 4/3 standards being around the same size as the Olympus 12-40mm f/2.8. Pro. However it feels well balanced on the OMD EM1 ii and Panasonic GH5. I never felt that the size of the lens was an issue. In fact I prefer the size of this lens over something smaller like the 25mm 1.8 as it just matches up with the larger Micro 4/3 bodies better.

Construction is impressive as it feels solid and well made. The focus ring is buttery smooth and allows you to easily and accurately manual focus when necessary. The lens features a clutch mechanism which you simply pull back to engage manual focus or push forward to be back in auto focus again.

The only criticism I would have is that the focus clutch mechanism is a little too easy to move so sometimes when picking it up out of my bag I knock it into manual focus by accident.

I can vouch for the excellent weather sealing on this lens as it withstood many Asian downpours while attached to the EM1 ii and I never had any problems at all with it.

It auto focuses quickly and accurately on the Olympus OMD EM1 ii and GH5. It is incredibly quick to focus and combined with eye detect AF makes shooting portraits a breeze.

There isn’t really a huge amount more to say on the handling of this lens. It is impressive and if you don’t mind the size then you will not be disappointed.

Olympus 25mm 1.2 Pro review – Image quality

I bought this lens and was expecting great things from it as Olympus has made a big deal about the image quality and in particular the quality of the ‘feathered bokeh’. Is this all marketing hype or is this lens really something special and worthy of the price tag.

In terms of sharpness I am not particularly interested in MTF charts and DXo scores. They tell me very little. What really tells me if a lens is sharp is if it looks sharp to me when I examine my images in Lightroom.

I shot a lot of portraits with this lens and the test for me is always when looking at eyebrows and eyelashes. I want to see if they are clearly defined or not.

Lets take a look at some samples below:

As you can see when shot wide open the Olympus 25mm 1.2 pro is incredibly sharp for a 1.2 lens. It renders the details of your subject beautifully and indeed offers some of the smoothest and creamiest bokeh I have seen. The bokeh is not busy or nervous at all and to my eye is very pleasing.

There is also a quality to the photos taken on this lens that you just do not find on many lenses. Your subject pops but because of the smooth transitions from in focus to out of focus the images feel very natural. In comparison to the Pana Leica 25mm 1.4 the images feel more organic and less digital. The Pana Leica is a lovely lens too and seems to offer more of a 3D pop to the images making your subjects  look very 3 dimensional and thus stand out from the background. However I find the rendering of the Olympus more natural and pleasing. The Pana Leica’s bokeh is a little more busy.

At f/1.2 the lens is already sharp and it gets a little sharper as you stop down to 1.4 -2. I would say the Pana Leica is perhaps a little sharper wide open but both are easily sharp enough for me.

The Olympus 25mm 1.2 Pro controls CA very well.

I didn’t experience any issues with lens flare and I was often shooting in broad daylight with strong sunshine.

Olympus 25mm 1.2 Pro Review – Conclusion

So would i recommend the Olympus 25mm 1.2 Pro?

That is a resounding yes. It is my favourite lens and in my time in Asia with it I only took it off my EM1 ii once and I regretted it. I absolutely love this lens for the fast aperture and build quality but most of all for the superb image quality and beautiful rendering. It allows you to create images that you just cannot get with other 25mm lenses and it means that I can shoot those images in to the night while keeping my ISO to 1600 and below.

If you can afford it and like the focal length then I can highly recommend this amazing lens. You will not be disappointed.

Last Updated October 23, 2025:
I recently noticed this older post still getting traffic, so I thought it deserved a refresh — especially since it was first published back in January 2018. I still shoot with Olympus (now OM System) as one of my main setups, and despite today’s full-frame obsession, I continue to rate it very highly — particularly for travel photography.

While both of these cameras are now considered “old,” don’t let that put you off finding a used bargain. They remain perfectly capable of producing excellent images, even if they lack the bells and whistles of modern bodies.

Since writing the original version, I’ve owned every E-M1 and OM-1 series camera, and they’ve improved dramatically over the years. I’ve also owned the GH6 and GH7 — and in my opinion, for photographers, the GH5 still stands as the pinnacle of the GH line.

Intro

In this article I am going to compare the Olympus OMD EM1 Mark II vs the Panasonic GH5. I own both of these top of the range Micro 4/3 cameras.

I have been using them for a few months now with a variety of different lenses and for different types of photography including landscapes, portraits and travel.

There are loads of comparisons on line that deal with the video side of things far better than I ever could as a primarily stills photographer. However despite the often stated presumption of using Olympus for stills and Panasonic for video I thought it would make an interesting comparison to see if this still holds true with these two flagship Micro 4/3 cameras.

Specifications at a glance

So let’s get straight into the comparison by looking firstly at the specs and then on to ergonomics and handling.

• Both have the latest 20mp Micro 4/3 sensors
• Both shoot 4k video although the GH5 has many more options including super slow motion full HD at 180fps as well as higher bit rates.
• The EM1 II has a 3 inch touch screen LCD and 2.36 million dot viewfinder
• The GH5 has a larger 3.2 inch touch screen LCD and 3.6 million dot viewfinder
• Both are weather sealed down to -10c
• The Olympus can shoot at up to 60 fps with the electronic shutter and 15 FPS with the mechanical shutter
• The GH5 shoots at 11 FPS
• Both have in-body 5 axis image stabilisation
• Both have a variety of shooting modes including time-lapse, HDR and focus bracketing

So let’s look a little bit beyond the specs and see what the cameras are actually like to handle.

Handling and Ergonomics

First up the Panasonic GH5 is 139x98x87mm and weighs 725g with the battery in. I might note it’s the same battery as the GH4 which is great if you already own some. Compare this with its predecessor the GH4 at 133x93x84mm and with a weight of 560g with battery and you can see that the GH5 has put on a considerable amount of weight and some heft too. Where I really notice this most is in the depth of the grip. It is very comfortable but I have to be honest and say I prefer the GH4’s grip.

The Olympus OMD EM1 mark II is slightly larger than its predecessor at 134x91x69mm and lighter too at 574g but still feels svelt in comparison to the GH5.

Both cameras feel great in the hand and are very comfortable to hold, even with larger lenses attached. However the GH5 is starting to feel quite large for a Micro 4/3 body. A lot of people (myself included) use this system for its light weight and portability.

I personally prefer the size and weight of the Olympus OMD EM1 Mark II. When I had both cameras on me in Asia recently I found myself gravitating towards the Olympus when given a choice. It was the one I naturally reached for out of the two. The reason is not just the size and weight but the fact that I also find the grip more comfortable. The grip on the GH5 is just a little too deep and results in your hand feeling the strain on extended use.

Controls and Menus

In terms of controls, both of these cameras are incredibly customisable. You can set them up virtually as you want. However one of the benefits of the larger body on the GH5 is more function buttons and more direct access buttons to things like ISO, white balance and exposure compensation. If you are used to the direct controls of a DSLR then the GH5 will feel more natural to you.

The Olympus takes a little more setting up initially but once you have set it up to your liking then you rarely have to delve in to the menu system during everyday shooting. The Panasonic just make sense and is very logical and intuitve in its control layout. I really can’t find fault with it. Picking it up for the first time everything was just where I would expect it to be and using it comes very naturally to me.

As for the menu systems themselves, the GH5’s menu is a little better set out and more intuitive to use thanks to a simple layout and straight forward logical ordering. The Olympus on the other hand does take a little getting used to with some odd naming of items such as noise reduction being called the noise filter etc. However once you are used to it then even the Olympus is quick and easy to navigate through. Top marks to Panasonic here though as I feel their menu system is one of the best available and having used loads of different cameras I find that everything is where I would expect it to be.

One new addition for the Panasonic GH5 is the AF joystick which has been added to the back of the camera. This allows direct access to change your AF point and it is a joy to use. Not only does it enable you to change your AF point more quickly but when clicked it also returns the AF point to home (default is centre point). Panasonic have implemented this brilliantly. There is also a switch which lets you quickly flick between AF-S, AF-C and manual focus.

The Olympus on the other hand relies on the D-Pad and while it is quick to use I do prefer the AF joystick of the GH5 and I’m sure most people would too.

Image Stabilisation

One of the big new additions to the Panasonic GH5 over the Gh4 is in body image stabilisation. Traditionally this has always been one of the big advantages that Olympus had over Panasonic.

However now that Panasonic have added this to the GH5 it really is a great improvement. Not only does it allow you to handhold shots at much lower shutter speeds enabling you to use a lower ISO but I also find it results in a much higher keeper rate for virtually all photos that you take.

So how does the image stabilisation compare between these two models.

Olympus claims 5.5 stops of stabilisation on the EM1 Mark II and Panasonic claims 5 stops on the GH5.

In my testing I found that I could comfortably handhold the Olympus at shutter speeds as low as 1-2 seconds at 12mm and still consistently get tack sharp images. Some even claim shutter speeds as low as 10 seconds are possible but I think that is a bit hit and miss and requires propping yourself up against a wall or tree to try and minimise any movement in your body.

With the GH5 I was able to consistently get tack sharp images at 1/3 second at 12mm on the Olympus 12-40mm f/2.8 Pro lens ( see my review of the Olympus 12-40mm f/2.8 Pro lens here ). So while the Olympus does still hold an advantage in this area the Panasonic certainly puts up a respectable fight.

Auto Focus, Burst rates and action

Both of these cameras are built for speed.

The Olympus boasts an incredible 60 fps burst rate  (single AF only) and 18 FPS with C-AF with the electronic shutter . These drop down to 15 FPS (S-AF) and 10 FPS (C-AF) with the mechanical shutter.

The GH5 while not as fast still offers very reasonable rates of 12 FPS (S-AF) and 9FPS (C-AF). So if you actually ignore the headline grabbing rates of the Olympus and look at the most useful option which is C-AF with the mechanical shutter there is on 1 FPS difference between the two.

So how do these two cameras handle fast action. 

I’m going to say straight up here that I am not a fast action shooter. I do portraits, landscapes and travel photography. However just in my simple testing having models walk through the scene I found that the Olympus AF system copes better and gives a higher keeper rate than the GH5. Although the GH5 has more focus points at 225 vs Olympus’ 121, the EM1 II uses a hybrid system of phase detect and contrast detect points that seem better able to keep up with movement.

Panasonic’s Depth from Defocus contrast detect system struggles a little bit more when it comes to C-AF and tracking auto focus.

Olympus also captures images at any of its high frame rates in full raw resolution. Pro capture is a feature which will pre record 14 images and constantly hold them in the buffer. Then if you start shooting you will be able to select from those pre-recorded images. It allows you to capture shots where maybe your trigger finger wasn’t quite fast enough.

Panasonic on the other hand offers 6k photo mode which allows you to continuosly record at 30fps and then extract 18mp still images from the recording but only in Jpeg format.

If I’m honest I find the implementation of Panasonic’s 6k photo mode more useful than Olympus’ due to one factor. With the Olympus you have to trawl through and delete any images that you don’t want. With the Panasonic you still have to look through all the images but you can simply select the ones that you want to keep. That saves me having to constantly delete multiple photos. However I rarely find myself using either of these options as I prefer a more considered and slower paced approach to photography but I understand birders, wildlife and sports photographers would appreciate them. Basically you can choose between the Raw files of the Olympus or the Jpegs of the Panasonic.

Standard focus performance from both is excellent

When it comes down to what I use most which is S-AF in single shot mode both cameras are brilliant in good light. They lock on quickly and are incredibly accurate. When the light drops slightly the Olympus is a tad better but there really is not much in it.

One thing I did notice while testing the Olympus 25mm 1.2 Pro on the GH5 was that a strongly back-lit scene could throw the GH5 off and it would hunt or in some cases fail to focus altogether.

When it comes to how I use these cameras I would take both of them over a DSLR any day of the week because they  just focus much more accurately.

Let’s not forget that both offer face detection and eye detection which is so useful for portrait work. Both work well but I prefer Olympus’ implementation as it adds a square over the face and then a smaller one over whichever eye is in focus. Panasonic puts a square around the face but then has intersecting lines to show you which eye is in focus. It is not quite as intuitive as the EM1 II and on occasion the intersecting lines do not meet over an eye so I was unsure as to whether the eye was in focus or not.

Image Quality and Colour Science.

Both cameras are using the latest Micro 4/3 20mp sensors so they should be quite evenly matched. However there has always been a notion that you use Olympus for stills and Panasonic for video but does this still hold true with the latest generation of cameras.

In terms of IQ the two cameras are virtually identical, offering sharp detailed photos. The GH5 removes the AA filter but in practise I have not noticed this to offer any tangible benefit. Both cameras seem to resolve the same level of detail.

One area where there is a slight difference is that the Olympus offers an extended ISO setting of 64 compared to that of 100 with the GH5. This does allow the EM1 II to give incredibly clean results with none of the noise that used to be present at base ISO in clear skies. This is a big improvement for me personally with my landscape work.

In terms of high ISO performance the two cameras are very evenly matched offering very usable files even at 3200 ISO and even 6400 ISO if the photos are just for web use or small prints.

At up to 800 ISO images are very clean and retain detail. At 1600 ISO you can see a slight loss of detail but no noise. At 3200 ISO there is further loss of detail and some noise creeping in to the images. At 6400 ISO details become smeared and noise is quite visible.

One thing that I have seen is that the Panasonic GH5 seems to handle colour noise a little better than the Olympus EM1 II at higher ISO settings. At 3200 the Olympus sometimes shows some ugly colour noise in skin tones whereas the Panasonic doesn’t. This is in the Jpeg files but not present in the raw files so if you shoot raw then it is nothing to be concerned about. If you shoot jpeg it is worth being aware of.

The colours on the GH5 have been improved quite a lot and I particularly like their natural profile for almost all types of imagery. The L Mono setting also gives very nice high contrast black and white shots. The natural profile on the Olympus is still the one I go to for most images and of course you can tweak the black and white profile in both the highlights, shadows and mid-tones to get it exactly as you wish.

Dynamic range of the two cameras is essentially identical.

I’ll be adding some high ISO examples soon. Having just gone through all my photo from these two cameras I realised that I don’t have good test shots to share because I was using the Olympus 25mm 1.2 (see my review here )and Pana Leica 25mm 1.4 a lot of the time and that allowed me to keep my ISO to 1600 or below at all times while in Asia.

Olympus does have a trick up its sleeve to best the GH5 for stills imagery in the form of the Hi Res mode. This combines 8 images in camera using sensor shift technology to give one hi resolution image.

I have found that this worked better in the EM1 Mark II than on my old EM5 II. It deals with movement better. For instance it is usable for running water now. However movement in trees and grass etc can still leave issues in your images that means this mode is only really fully usable for things like product photography. Let’s hope Olympus can improve Hi Res mode further as it has so much potential.

To use Hi Res mode you have to have the camera locked down on a sturdy tripod. I use the Manfrotto 055 XPRO3 which is absolutely rock solid.

You also need to be using very sharp lenses to really take advantage of this and resolve all the detail.

Another area where the Olympus EM1 II has an advantage is in night photography. Live view, live boost and live composite really are very useful as they allow you to see the image on the LCD screen as it is being created. It gives you a live preview as the exposure is taking place so you know exactly when you have the correct exposure and can stop at the perfect time.

Conclusion

So which camera is the better one for stills photography?

If you are not going to take advantage of Hi Res mode, Live view, Live bulb and Live composite then at £1699 compared with £1849 the GH5 is surely the logical choice with its better viewfinder, LCD and far better video features. It definitely offers the better value and can keep up with the Olympus EM1 Mark II for general photography use.

However having said all that I still prefer the Olympus EM1 II and here is why.

I prefer the handling of the Olympus. I use Micro 4/3 to keep the size and weight of my kit small and light. The Panasonic GH5 is just a little too large for my liking and I prefer the grip on the Olympus which is more comfortable to hold all day long.

The GH5 does have good ergonomics and I particularly like the AF joystick and direct access to ISO via a dedicated button but I am quite happy using the D-pad to move AF points on the EM1 II and I can assign almost any button on the EM1 II to give me quick access to ISO. In all honesty if I am shooting in situations where the ISO needs changing quickly then I will have either camera set to auto ISO and set a maximum ISO and minimum shutter. If I want to set the ISO manually such as when shooting landscapes then quick access is not so vital and a quick press of the OK button and I am in to Olympus’ Super Control panel.

I find the auto focus on the Olympus just a touch more reliable in low light and I prefer their implementation of face detect AF. These two things can and did make the difference between me getting a candid shot of my daughter and not.

Lastly and this is a very subjective thing but I find the Olympus OMD EM1 II to be a beautiful camera and the finish in my opinion feels higher quality and more refined. It just works so well. In fact I would say that ergonomically it is the best camera that I have ever used and in the end this factor more than specs make me want to pick it up and take it with me everywhere.

So which one should you chose?

My brain finds it hard to recommend the Olympus OMD EM1 Mark II over the Panasonic GH5 at this time but my heart would chose the Olympus each and every time. However I will be keeping both as they are two of the best cameras available right now and whichever one you choose I’m sure you will be delighted.

Update January 2026. It’s hard to believe just how long ago it was since I wrote this review. I stand by the fact that the Olympus 12-40mm f/2.8 Pro is still a fantastic lens and one that I used for years. I am heading back to the UK next week, where I will pick up my OM1 Mark II and the OM System 12-40mm f/2.8 Pro mark II. Essentially the same lens. That says a lot about how I regard this lens. I still use the newer version, to this day, 8 years later. In fact I’ve just featured it in my best lenses for travel photography with the Om-3 article. Stay tuned for more OM Systems articles coming soon. You can see my OM1 review here and why I bought the OM-3 here.

In this Olympus 12-40mm f2.8 review I will go through the pros and cons of this professional grade zoom lens after having used it for well over a year in my personal and professional work.

The Olympus 12-40mm f/2.8 was the first in Olympus’ Pro series of lenses designed for Micro 4/3 cameras. It is a weatherproof (dust, splash and freeze proof) fixed aperture zoom lens offering the 35mm equivalent field of view of a 24-80mm lens. It has a fixed aperture of f/2.8 throughout the zoom range with a filter thread of 62mm.

Build Quality

The first thing you will notice when you pick up the 12-40mm is the build quality. Like all of the Olympus Pro range of lenses it is extremely well made. At 382 grams and featuring a metal construction it feels solid in the hand and inspires confidence in use. For me it fits perfectly on the Olympus E-M5 II with the HLD-8G grip attached or on the EM1 and Em1 II giving you a weather sealed combination.

There is also an additional function button on the lens which you can program to activate a variety of features by simply customising it in camera.

While it is a larger lens for Micro 4/3 in comparison to some of the tiny primes, it is not oversized and much smaller than something like the Canon 24-70mm f/2.8. You can carry it attached to your camera all day and not notice the weight.

Olympus 12-40mm f2.8 Review – Focus

This is going to be a very quick section because all there is to say is that focus is as fast as any lens on the system. It is instantaneous to focus and is deadly accurate. Absolutely no issues here.

The zoom ring is nicely damped and it features a manual focus clutch mechanism that allows you to easily swap between auto and manual focus simply by pulling the clutch back or pushing it forward. It uses focus by wire but don’t let that put you off as the focus ring is incredibly smooth and allows you to easily and finely adjust your focus.

Zoom markings are shown for 12, 14, 18, 25, 35, and 40mm. If you pull back on the focus ring you put the lens into manual focus mode and reveal a focus scale. The focus scale has markings at 1’, 2’, 5’, and .2m, .5m, and 1m, plus infinity. Close focus is 8” (0.2m), and the lens can produce a 1:3.3 magnification ratio at 40mm.

The Olympus 12-40mm zooms externally so it increases in length from 3.3″ -5″ when extended.

Olympus 12-40mm f2.8 Review – Image Quality

The 12-40mm pro does suffer with some barrel distortion at the wide end if you shoot raw. The Jpegs are corrected in camera and the software does a good job in most cases. At 40mm there is a slight amount of pin cushion distortion. If you are shooting raw and have straight lines in your shots then you will need to correct in post.

The lens also shows some vignetting when wide open at f/2.8. This is easily corrected in post. I guess Olympus tried to keep this constant f/2.8 zoom as small as possible and that means the image circle only just covers the micro 4/3 sensor.

This lens handles chromatic aberration very well and I see very little sign of fringing even when shooting high contrast scenes. It also handles flare well.

The Olympus 12-40mm is sharp from 12mm all the way through to 40mm even wide open at f/2.8. At 12mm the corner performance is slightly softer than the centre but still way better than something like a Canon 17-40mm L. As mentioned the lens is bitingly sharp in the centre at f/2.8 and performance increases slightly when stopped down to f/4.

While f/2.8 on the Micro 4/3 format does not offer the same shallow depth of field as on 35mm sensors it is still capable of allowing your subject to be isolated from the background as shown in the above portrait. The bokeh from the Olympus 12-40mm f/2.8 at 40mm is enough for portrait work and the rendering is smooth and not overly busy. While it couldn’t be described as creamy it is not nervous and distracting and so works well. If you want a dedicated portrait lens then I suggest that you check out my Olympus 75mm f1.8 review or 45mm 1.8 review

Conclusion

Overall I would rate the Olympus 12-40mm f2.8 as one of the best zooms I have used. It is very well-built and combined with my EM5II or an EM1 series body offers excellent weather-sealing and a very useful focal range.

In terms of image quality sharpness is outstanding throughout the zoom range enabling you to shoot it wide open at f/2.8 without concern. It can do everything from wide-angle landscapes to portraits and it does it all well. Yes other lenses may be better at specific roles but none offer the versatility and fixed bright aperture of this lens.

If you are trying to decide between this lens and the Panasonic 12-35mm (mark i or mark II) then it really comes down to a few factors as optically they are very similar. The Olympus is better at the wide end and offers a little more range at the long end. However the Panasonic is slightly sharper at 35m than the Olympus is at 40mm.

If you are shooting on a Panasonic body then perhaps you might prefer to go with the Panasonic lens to take advantage of Panasonic’s depth from defocus system and in the case of the mark ii lens their dual sync IS. The Panasonic lenses are both lighter than the Olympus.

However having owned all 3 lenses and as an owner of the Panasonic GH5 and Olympus EM5 II I decided that the build quality of the Olympus 12-40mm edged out the Panasonic and so I kept it over its rivals. When I say edged out, it is night and day. The Panasonic’s feel like a consumer grade lens with very good optics. The Olympus 12-40mm feels like a professional grade lens in every way.

During my testing, dual sync IS between the GH5 and 12-35mm ii made no noticeable improvement in the image stabilisation and didn’t allow me to handhold shots for any longer than when using the Olympus 12-40mm f/2.8 on the GH5.

If you are going to own just one lens for Micro 4/3 then this may very well be the best choice. Make sure to check out my Olympus 25mm 1.2 Pro review as well.

I recently bought the OM System OM-3 and would have picked up the little 45mm again, but it looks like OM System are in the process of updating their 1.8 lenses with weather sealing. I’ve already added the new 17mm f/1.8 Mark II to my kit (review coming once I’ve had more time with it) and am holding out for the updated 45mm f/1.8 Mark II before re-purchasing it for use with my OM-3 and OM-1 Mark II. In the mean-time to see more recent OM Systems content take a look at my comprehensive OM-1 review.

Back to the review:

If you are looking for the best value portrait lens in the World then I think I may have the answer for you.

For many years now I have been shooting a variety of cameras and lenses ranging from Micro 4/3 to large format 4×5 film. As I am not rich I like to get the best gear that I can afford that will do the job I need it to do.

With that in mind I have used many different lenses and for portraits I have found that the Olympus 45mm f/1.8 lens offers the best value of any lens for portrait shots. It comes in at around £200 and is as sharp as you need for portraits. In fact it is pretty sharp wide open at f/1.8 and gets a little sharper when stopped down to f/2.8-5.6.

So below I am going to show why I think it offers great value and is basically a must have lens for every Micro 4/3 photographer.

Don’t forget that you can really help me out by buying this lens through the links on this page. I will earn a small commission and it won’t cost you a penny more.

Olympus 45mm 1.8 – Handling

There is nothing outstanding about the handling of the Olympus 45mm f/1.8. It is made of plastic and doesn’t feel particularly expensive. However it is still a notch above lenses like the Canon 50mm 1.8 (sometimes called the plastic fantastic). It feels decently made but certainly cheaper than other lenses such as the Olympus 75mm f/1.8 or Olympus Pro zooms. However it is perfectly functional and does what it needs to do.

The reason I mention handling is because it is such a small and light lens that you can easily add this to your bag or even in a pocket and not even notice the weight. This makes it a carry everywhere lens for me and if I was to only have a 2 lens setup the little 45mm would almost always be one of the two lenses that I would carry.

Image Quality.

More importantly, the reason why I think this lens offers such great value is because it offers really good image quality for the size and weight. It is sharp wide open and as mentioned before it improves a little when stopped down.

It easily defines eyelashes when shooting portraits which is one of my prerequisites for sharpness in a portrait lens.

It doesn’t suffer with any major flaws in terms of CA or distortion. Therefore for the price you get a very handy high quality lens that doesn’t add much weight to your setup. The only criticism I could level at it is that sometimes the bokeh can get a little nervous so you have to watch your background sometimes. However you should always be doing that anyway.

The f/1.8 aperture allows it to be used in low light and maintain fast enough shutter speeds to get sharp people images and the focal length is my personal favourite for portrait work.

Below are a few images taken with the 45mm f/1.8.

Olympus / OM System 45mm f/1.8 FAQ

Is the OM System 45mm f/1.8 still worth buying?
Yes. Despite its age, the 45mm f/1.8 remains one of the best value portrait lenses available. It offers excellent sharpness, pleasing subject separation, fast autofocus, and a compact size at a very low price point.

What focal length is the 45mm f/1.8 equivalent to?
On Micro Four Thirds, the 45mm f/1.8 is equivalent to a 90mm lens on full frame. This makes it ideal for portraits, headshots, and isolating subjects.

Is the 45mm f/1.8 sharp wide open?
Yes. The lens is already sharp at f/1.8, especially for portrait work, and improves slightly when stopped down to around f/2.8–f/5.6.

Does the OM System 45mm f/1.8 have weather sealing?
No. The original version of the 45mm f/1.8 is not weather sealed. OM System appears to be updating its f/1.8 prime lineup, so a weather-sealed Mark II version is expected.

How does it compare to the Olympus 75mm f/1.8?
The 75mm f/1.8 offers better build quality and more subject isolation, but it is larger, heavier, and significantly more expensive. For most photographers, the 45mm f/1.8 is the more practical and better-value option.

Is the autofocus good enough for portraits and everyday use?
Yes. Autofocus is fast, accurate, and reliable for portraits, family photography, and general use. It performs well even on older Micro Four Thirds bodies.

Is the OM System 45mm f/1.8 good for beginners?
Absolutely. Its low cost, light weight, and excellent image quality make it one of the best first portrait lenses for Micro Four Thirds shooters.

What camera bodies does the 45mm f/1.8 work with?
The lens is compatible with all Micro Four Thirds cameras, including OM System, Olympus, and Panasonic bodies.

This is not just any old Olympus OM EM5 II review. I have written this review after having spent nearly a year using this camera for travel, landscape and portrait photography. In this review I will tell you what is great and not so great about this small but powerful camera. So lets crack on and get into the review. If you are looking at higher end Micro 4/3 cameras then you might like my comparison of the Olympus OMD EM1 ii vs Panasonic GH5

Olympus OMD EM 5 II review – Build Quality and Handling

Let’s start with the build quality and handling of the EM5 II because for me in these days where almost all cameras produce high quality results I find myself more and more concerned with how a camera feels and handles.

The OMD EM5 II is a very well built little camera. It is constructed of a magnesium alloy body and is fully weather sealed. I have used it in everything from tropical rain to sub zero temperatures and it has functioned faultlessly.

The body weighing in at 469g feels dense and solid. Unlike Fuji cameras which often have a slightly hollow feeling. It is a little larger and heavier than the Mk I at 124x85x45mm  but I also find it more comfortable to hold. This is thanks in part to the thumb rest (which extends out a little further) and the increased grip size on the front.

The buttons on the camera also lose the slightly spongy feeling of the mark 1 and as a result give better tactile feedback when in use.

The dials on the mk II are larger and the power switch has been re-positioned to the top left of the camera a la the EM1.

The 3 Inch fully articulated LCD screen feels robust and not in danger of snapping off or becoming a weak point. Let’s not forget that this little camera is weather sealed against dust, water and it is also now tested to be freeze-proof.

The only issue I have had in the handling department with the Olympus OMD EM5 II is the tendency for the rubber viewfinder eye piece to get knocked off when taking it in and out of my bag. So I would advise that you keep an eye on it to make sure you don’t lose it.

I would also mention that in its default state the startup time can be slow. It can also be tedious when the eye sensor is turned on and you switch between the LCD and EVF. I personally turn off the eye sensor and shoot only through the EVF. Leaving the LCD for reviewing images. This greatly speeds up operation of the camera.

I like the modular nature of the OMD EM5 II. What do I mean by this? Well I would advise any owner to at least pick up the HLD8G part of the battery grip because it really adds to the handling of the camera when using larger lenses. I find that with the HLD8G grip added the camera handles very similarly to my old EM1. It feels just right with larger lenses like the Olympus 12-40mm f/2.8 Pro attached. Of course with this combination you now have a very well weather sealed camera and lens combination that can take in just about any climate.

But of course you also have the choice to go small and light when you wish by removing the grip and using smaller prime lenses like the 25mm 1.8.

Olympus OMD EM5 II Review – Features

• 16mp Micro 4/3 sensor
• In-built 5 axis image stabilisation
• 40mp Hi res mode
• 1080/60p shooting and 1080/30p at up to 77Mbps (All-I)
• 1/8000th sec maximum shutter speed (1/16000th with electronic shutter)
• Built-in Wi-Fi
• Live Bulb and Live time for easy long exposure photography

Let’s talk about that 16mp sensor because some may feel it is lacking compared to many competitors today where they are regularly offering 20-24mp on larger APS-C sensors.

While the 16mp sensor doesn’t quite keep up with competition anymore it is still perfectly capable of giving detailed images that can easily be used for everything from social media to prints up to 30×20″ with proper technique.

Dynamic range is on par with larger APS-C sensor offerings from Fuji and Nikon (see my Micro 4/3 vs APS-C comparison here).

Up to ISO 3200 is perfectly usable and the grain from noise is not unsightly.

Below are a couple of samples from shots taken at ISO 3200. Test charts don’t really give you a clear idea of real world noise performance. I find that the real test is shooting portraits and seeing how the camera does with skin tones. Both of these are 100% crops.

Olympus also offers a Hi Res mode which gives 40mp files that both improve the detail and colour accuracy of the images. It is an incredible feat. However the caveat is that you really need to lock your camera down on a solid tripod and have minimal to no movement within the scene. It is workable with landscape images and is certainly very useful for studio product and architectural photography.

The image stabilisation within the EM5 II is one of the standout features of this camera. At 24mm I can comfortably hand hold shots at 1 second which has several benefits. Firstly it allows you to lower the shutter speed and keep the ISO low, resulting in better quality photos with less noise. This somewhat negates the benefits of larger sensor cameras if your subjects are stationary.

Secondly it allows you to feel comfortable heading out with your camera without a tripod.

The 1/8000 of a second fastest mechanical shutter speed means that even using fast prime lenses in broad daylight is usually not an issue.

Video has been improved on the EM5 II over the original and the quality is decent enough for travel use and V-Logging. You can even shoot time lapse and slow motion in camera. However the video image is nowhere near as sharp as that given by recent Panasonic cameras.

I also find myself using the handy Olympus Viewer app to transfer images from the camera to my phone for quick uploading to social media. Unlike Fuji there is no 30 picture transfer limit. The app is simple and functional, allowing you to also leave your shutter release at home as you can trigger the camera from it.

The viewfinder on the EM5 II is taken directly from the EM1 and is larger than the one found on the Olympus Pen F for example. It is not the largest EVF in the world, with those from the Fuji XT2 and Panasonic GH5 offering a better experience. However it is large enough to manually focus lenses and see all the details that you will need to capture the moment.

With really useful tools in camera such as Live Bulb and Live Time you can capture long exposures while being given a preview on the LCD screen as the image builds. This is one of the standout features of Olympus cameras at the moment and genuinely useful.

Olympus OMD EM5 II Review – Verdict

So why am I reviewing the Olympus OMD EM5 II when it has been out for a couple of years now and its replacement is expected in a few months time.

Well in this day and age with companies constantly bombarding us with their marketing telling us that we need the latest and greatest in order to be good photographers, compete with everyone else etc, I wanted to show that this 2 year old small sensored camera is still perfectly capable of producing professional quality results in a small package with all the features you are likely to ever need.
