Sharpness Cont... 2
Sharpness at 50mm
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 50mm
Sharpness in the centre of the frame is commendably high even wide open at f/5.3 and gets better still at f/8. Stopping down further brings no perceivable benefit in terms of sharpness.
The borders and corners are clearly softer but still adequate, with f11 being the best setting.
