Sharpness at 58mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Nikkor 58mm f1.4 lens was attached to a Nikon Df body, which in turn was mounted on a sturdy tripod. Exposure Delay Mode was activated. Slight tonal changes are due to slight changes in natural light during the session.

The full frame at 58mm

The lens is soft wide open at f/1.4, not sharpening up until f/2.8 in the centre and f/4 at the edges. From f/2.8 through f/11 in the centre, sharpness is outstanding, and f/16 is only slightly worse.
