Sharpness at 35mm

For this test, the Nikon Z 35mm f/1.4 lens was attached to a Nikon Z7 II 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

The centre is a little soft wide open at f/1.4, sharpening up at f/2, with peak performance achieved in the f/2.8-f/11 range. Diffraction starts to set in at f/16.

The edges are almost as sharp as the centre, with f/2.8 to f/11 again being the optimum settings.
