Sharpness at 35mm

For this test, the Nikon Z DX 16-50mm F3.5-6.3 VR lens was attached to a Nikon Z fc body, which was in turn mounted to a sturdy tripod. Exposure delay mode was activated. Tonal and colour variance across the crops are due to change in natural light during the session.

The full frame at 35mm

Centre sharpness is excellent wide-open at f/5.3 through to f/11, with f/16 to f/32 being adversely affected by diffraction.

The edges aren't as sharp as the centre, with f/8 to f/11 producing the sharpest results.
