Nikon Z 24-70mm f/4 S Review
Sharpness at 24mm
For this review, the sharpness test is carried out by photographing a real-world sample, rather than a test chart. The Nikkor Z 24-70mm f/4 S lens was mounted on a Nikon Z 7, which was in-turn mounted on a sturdy tripod. Exposure delay was activated to prevent camera-shake. Any changes in tone you might see across the crops are due to natural light changes during the shooting session.
The full frame at 24mm
At the widest focal length of 24mm, sharpness is fantastic at the widest aperture of f/4. It remains excellent at f/5.6, softening just a little at f/8. The image is a little softer again (but still very good) at f/11, while f/16 and f/22 show the least amount of sharpness in the centre - the overall impression of detail when viewing the image at normal sizes remains excellent however. At the corners of the image, the best sharpness can be seen between f/8 and f/16, dropping off a little at the narrowest aperture of f/22.
