Sharpness Cont... 3

Sharpness at 24mm

For these sharpness tests the Nikon 10-24mm lens was attached to a Nikon D7000 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 1/400th of the total frame area.

The central areas are remarkably sharp even wide open, with sharpness peaking at f/8. Edge sharpness, though never quite as high as in the centre, is also very good and fairly consistent from f/5.6 through f/11.
