Sharpness at 14mm

Our sharpness tests are carried out by photographing a real-world subject rather than a test chart. The Nikkor Z 14-30mm 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 14mm

At the centre of the image, sharpness is very good at the widest aperture of f/4. It is even better at f/5.6 and f/8, before dropping again slightly at f/11 and again at f/16. It is least sharp at f/22, but it’s still pretty good - and the drop in sharpness is not too noticeable unless examining an image at 100%. At the edge, sharpness is best between f/5.6 and f/8.
