Sharpness Cont... 3

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 18-300mm f/3.5-5.6G VR lens was attached to a Nikon D7000 body, which in turn was mounted on a sturdy tripod. We also used an infrared remote release and mirror lock-up to prevent any blurring that may result from camera or mirror movement. 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 full frame at 105mm

Centre sharpness at 105mm is good wide open at f/5.6, with f/8 being better still. Stopping down further brings no benefits, with resolution being limited by diffraction.

Edge performance is decent, with f/11 being the sweet spot.
