Nikon AF-P DX Nikkor 10-20mm f/4.5-5.6G VR Review
Sharpness at 20mm
For these sharpness tests the Nikon 10-20mm lens was attached to a Nikon D500 camera body, which in turn was mounted on a sturdy tripod. Slight tonal changes are due to slight changes in natural light during the session. The 100% crops represent about 1/500th of the total frame area.
The full frame at 20mm
The central areas are pretty sharp – although not “bitingly” so – wide open at f/5.6 and do not improve upon stopping down to f/8. Diffraction takes its toll on image quality at smaller apertures, although the lens remains usable through f16.
The situation is somewhat different around the edges, where peak sharpness is achieved at f11.
