Canon EF-S 17-55mm f/2.8 IS USM Review

Sharpness at 20mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Canon EF-S 17-55mm f/2.8 IS USM lens was attached to a Canon EOS 700D body, which in turn was mounted on a sturdy tripod. Self-timer mode was activated. Slight tonal changes are due to slight changes in natural light during the session.

Centre sharpness remains high through from f4 to f/11, with f/16 and f/22 being adversely affected by diffraction. The edges are almost as sharp as the centre, with f/4 to f/11 again producing the sharpest results.
