Sharpness at 105mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Nikon AF-S Nikkor 105mm f/1.4E ED lens was attached to a Nikon D810 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 105mm

The lens is alittle soft wide open at f/1.4, becoming acceptably sharp at f/2 in both the centre and the edges. From f/2.8 through f/11 throughout the frame, sharpness is outstanding, and f/16 is only slightly worse due to diffraction.
