Sharpness

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Nikkor 28mm f1.8 lens was attached to a Nikon D3S 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 28mm

Sharpness is quite good wide open, fine at f/2.8, and nothing short of excellent between f/4 and f/11. At f/16, sharpness is still very high, although lens contrast is slightly lower than at the other settings. An impressive performance.
