The Nikon 50mm Z f/1.8 S
For years, I relied on 35mm and 75mm primes, appreciating the discipline they brought to composition. However, after moving to the Nikon Z system, I went with the 24-120 for flexibility. As with most photographers, GAS got the better of me and I decided I needed a smaller lens for general walk around photography. I wanted something that balanced portability with image quality, enter the 50mm Z f/1.8 S.
Sharpness & Optical Performance
The Nikon 50mm f/1.8 S is renowned for its incredible sharpness, and after using it, I can see why. Wide open at f/1.8, it delivers excellent centre sharpness with minimal chromatic aberration. Unlike older DSLR-era 50mm lenses, the Z-mount design allows for better optical correction, meaning edge-to-edge clarity is outstanding. Stopping down slightly enhances micro-contrast and fine detail even further, making it ideal for capturing both landscapes and portraits with striking clarity.

Size & Walkaround Usability
While the 50mm f/1.8 S is larger than other options for the Nikon Z mount, it remains manageable for daily use. It balances well on Nikon Z bodies, and despite its size, it doesn’t feel cumbersome during extended shooting sessions. The build quality also adds to its appeal, with a solid, weather-sealed design that gives confidence when shooting in varied conditions.
For a walkaround lens, the compact 40mm f/2 is certainly a more discreet option, making it great for casual street photography. However, I found that the slightly longer focal length of the 50mm f/1.8 S works better for my style, offering a tighter composition without being restrictive. The added sharpness also means I can crop in post without worrying about loss of detail.

Comparison to the 50mm f/1.4 & 40mm f/2
The 50mm f/1.4 offers a slightly faster aperture, but the f/1.8 S holds its own in sharpness, and with modern sensors handling high ISOs well, the extra light-gathering ability didn’t feel essential. The 40mm f/2 is a solid, compact option, but its optical quality isn’t quite at the same level, particularly at wider apertures. In the end, I prioritised outright image quality over size and speed, making the f/1.8 S the right choice for me.
Final Thoughts
The Nikon 50mm f/1.8 S isn’t the smallest or fastest prime lens available, but it delivers where it matters most to me…sharpness. Its not the fastest option on the market or the most functional (Nikon 50mm f1.4 has a programable ring) but I’m really enjoying this lens so far and i’ve managed to get a nice mix of decent photos with it already.
So if you’re looking for a high-quality 50mm prime for the Nikon Z system, this lens is an excellent choice especially if you can find a deal like I did.
