Instead, I’ve found myself using it not for traditional wide vistas and expansive views of the Highlands, but on local walks through ancient woodland and farmland. Rather than using it to capture grand landscapes, I’ve been using it to explore a different way of seeing and composing photographs.

As a result, this lens has spent far more time on my camera than I ever expected.

More Than Just a Landscape Lens

Initially, I took the Nikon Z 20mm f/1.8 S out on my Z6 III during a particularly stressful period.

I wanted to walk my local woodland, clear my head and spend some time outdoors. To simplify things, I deliberately chose a prime lens. Removing the option to zoom meant one less decision to make, while the bright f/1.8 aperture would help keep ISO levels under control on the dull, rainy days that are so common in Scottish woodland.

To be honest, I wasn’t expecting to come home with any great photographs. The goal was simply to get out of the house and decompress.

What I found while exploring local farm tracks and ancient woodland was unexpected.

The 20mm focal length encouraged me to really look and see in a way that zoom lenses often don’t. Its wide perspective forced me to pay close attention to every element in the frame, move closer to subjects, and think carefully about the relationship between foreground and background.

At the same time, the lens offered an unusual combination: I could get physically close to a subject while still including a strong sense of place and context. A patch of grass, a weathered fence post or a small group of trees could become the focal point of an image without losing the surrounding environment that gave it meaning.

As a result, composing photographs became a far more immersive experience. Sometimes it was challenging. Often it required more thought than simply zooming in on a subject. But when everything came together, it was also incredibly rewarding.

That experience is a large part of why the Nikon Z 20mm f/1.8 S has spent far more time on my camera than I originally expected. It encouraged me to shoot it more on my Nikon Z8 too.

Build Quality

Like the rest of Nikon’s S-Line prime lenses, the Nikon Z 20mm f/1.8 S feels exceptionally well made.

Constructed from a combination of high-quality plastics and metal, the lens strikes an excellent balance between durability and weight. At 505g, it isn’t the smallest wide-angle prime available for the Nikon Z system, but it is light enough that I’ve happily carried it for several hours while exploring local woodland and farm tracks.

It takes 77mm filters which is a standard filter size and happens to be one of the two sizes of filters that I managed to salvage from the Philippines when I moved to Scotland this year. That allows me to share filters between it and some of my other lenses such as the Nikon Z 24-120mm f/4.

Mounted on both the Nikon Z6 III and Nikon Z8, the lens feels well balanced. It’s substantial enough to inspire confidence without ever becoming burdensome, which is particularly important for a lens that often encourages longer walks and slower, more deliberate photography. The design is similar to the Nikon Z 85mm 1.8S lens in that Nikon have opted for a more narrow and long design rather than fat and short. I prefer fat and short but that’s very subjective.

The weather sealing is also reassuring. Much of my early use of the lens took place during typical Scottish weather, where damp conditions, drizzle and muddy paths are often part of the experience. I never felt the need to baby the 20mm f/1.8 S when shooting outdoors.

Image Quality

The Nikon Z 20mm f/1.8 S delivers excellent image quality and is one of those lenses that quickly disappears as a limitation when you’re shooting.

Wide open at f/1.8, the lens is impressively sharp in the centre of the frame whether mounted on the Nikon Z6 III or the higher-resolution Nikon Z8. Corner sharpness does soften slightly at wider apertures, but in practice I rarely found this to be an issue. If I’m shooting at f/1.8, my attention is usually on ensuring the subject is sharp rather than critically assessing corner performance.

Stop the lens down and the performance becomes even more impressive. Between f/5.6 and f/11, the Nikon Z 20mm f/1.8 S produces excellent detail across the frame, including the corners. On the 45.7MP Nikon Z8, images remain highly detailed even when viewed at 100%.

One aspect of the lens that particularly impressed me during woodland photography was its control of chromatic aberration. Backlit trees against bright skies are one of the harshest tests for any lens, yet the 20mm f/1.8 S handled these situations exceptionally well. Even in scenes with extreme contrast, I saw virtually no distracting colour fringing.

Flare resistance is similarly impressive. Nikon’s coatings do an excellent job of maintaining contrast when shooting into challenging light, while the supplied lens hood provides additional protection from stray light. Although no lens is completely immune to flare, the 20mm f/1.8 S performed very well in the situations I encountered.

As with any ultra-wide-angle lens, distortion is something you need to be aware of. Keeping the camera level is important if you want to avoid converging verticals and exaggerated perspective effects. Fortunately, Nikon Z camera’s built-in level makes this easy, and any remaining distortion is quickly corrected in Lightroom using the lens profile. In real-world use, I found the optical distortion to be relatively well controlled.

What stands out most about the Nikon Z 20mm f/1.8 S, however, isn’t its sharpness, lack of chromatic aberration, or flare resistance—impressive though those qualities are.

What makes this lens special is the way it encourages you to see. Its wide field of view pushes you to think more carefully about composition, relationships between subjects, and the use of foreground elements. It demands more attention than many lenses, but it also rewards that effort. The excellent optical performance simply ensures that when you do find a compelling composition, the resulting image lives up to the vision you saw in the field.

Autofocus Performance

Autofocus performance is exactly what I’ve come to expect from Nikon’s S-Line prime lenses. Focusing is fast, accurate and essentially silent.

In my use, which has mainly consisted of woodland photography, countryside walks and general outdoor shooting, the lens has never given me reason to think about autofocus at all. Focus acquisition is quick, subject detection works as expected, and accuracy has been consistently excellent on both the Nikon Z6 III and Nikon Z8.

Ultimately, autofocus is one of those areas where the Nikon Z 20mm f/1.8 S simply gets out of the way and lets you concentrate on making photographs.

Final Thoughts

I bought the Nikon Z 20mm f/1.8 S as a relatively lightweight wide-angle lens for those occasions when my Nikon Z 24-120mm f/4 S wasn’t quite wide enough.

What I didn’t expect was how much I would enjoy using it.

While the optical performance is excellent, with impressive sharpness, excellent control of chromatic aberration and strong flare resistance, those aren’t the reasons this lens has spent so much time on my camera.

The real appeal of the Nikon Z 20mm f/1.8 S is the way it encourages you to photograph differently. It rewards photographers who are willing to slow down, pay attention to the relationships between elements within a scene and think carefully about composition. In return, it offers a perspective that is difficult to replicate with other lenses.

It won’t be the right lens for everyone. Many photographers will be better served by the flexibility of the Nikon Z 14-30mm f/4 S or 14-24mm f/2.8 S, while others may find a 35mm or 50mm prime more useful for everyday photography.

However, if you enjoy working with a fixed focal length, appreciate the immersive perspective of a wide-angle lens and want something capable of far more than simply capturing expansive landscapes, the Nikon Z 20mm f/1.8 S is an easy lens to recommend.

For me, it has become one of the most enjoyable lenses in my Nikon kit.
