Sharpness at 140mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Nikon AF-S Nikkor 18-140mm f/3.5-5.6G VR lens was attached to a Nikon D7100 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. The 100% crops represent about 1/600th of the total frame area.

The full frame at 140mm

Sharpness at 140mm is very good from f/5.6 to f/11, with f/8 being the sweet spot. The f/16 setting is usable in a pinch but the f/22 and f/32 settings should be avoided.
