Sharpness at 50mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The AF-S Nikkor 50mm f/1.8G 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 50mm

The lens is acceptably sharp wide open at f/1.8, really sharpening up at f/2.8 in the centre and f/5.6 at the edges. From f/2.8 through f/11 in the centre, sharpness is excellent, and f/16 is only slightly worse due to diffraction.
