Sharpness at 20mm

Our sharpness tests are carried out by photographing a real-world subject rather than a test chart. The Nikkor Z 14-24mm f/4 S was attached to a Nikon Z7, which in turn was mounted on a sturdy tripod. Self-timer mode was activated to steady the camera completely. Any slight tonal changes you may see across the crops are a result of slight changes in natural light during the shooting session.

The full frame at 24mm

At 24mm, shooting at f/4 reveals a very sharp central part of the image. The image is sharper again at f/5.6 and f/8, before dropping off slightly again at f/11. Sharpness drops a little bit again at f/16, before producing the softest results at f/22 - but it is still very good at this focal length. At the edge of the frame, the sharpest results can be seen between f/8 and f/11.
