Sharpness Cont... 2

Sharpness at 135mm

For this test, the Nikon AF-S Nikkor 55-300mm f/4.5-5.6G VR lens was attached to a Nikon D7000 body, which in turn was mounted on a sturdy tripod. Exposure delay mode was activated. Tonal and colour variances across the crops are due to changes in natural light during the session. The 100% crops represent about 1/400th of the total frame area.
