Nikon Z 14-30mm f/4 S Review
Sharpness at 20mm
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 20mm
At wide open (f/4), and shooting at 20mm, sharpness is excellent. It remains excellent at f/5.6 and f/8, becoming a little less sharp at f/11, dropping again at f/16 and with the least sharpness visible at f/22. This shouldn’t be too problematic if printing images at normal sizes. The sharpest results for the edges of the image are again between f/5.6 and f/8.
