Sharpness at 35mm

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 35mm

At the centre of the image, sharpness is fantastic at f/4. It stays excellent at f/5.6 and f/8, with a little more softness at f/11. Sharpness drops again at f/16, being the softest at f/22. At regular printing or viewing sizes, the overall impression of detail is still good. At the edges of the images, the best sharpness can be seen between f/8 and f/16.
