Canon EF 70-300mm f/4.5-5.6 DO IS USM Review

Sharpness Cont... 5

Sharpness at 300mm

Sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Canon EF 70-300mm f/4.5-5.6 DO IS USM lens was attached to a Canon EOS 5D MkII for this test and mounted on a Manfrotto tripod. A short two second self timer was used to reduce vibration as well as the mirror lock up mode. Photographs were taken indoors in ambient light so any changes in colour or exposure are due to that.

Leaving the centre of the focal range and going back to the extreme end, the variation in sharpness appears at the wide and narrow end of the aperture settings.
