Canon EF-M 28mm f/3.5 Macro IS STM Review
Sharpness at 28mm
The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Canon EF-M 28mm f/3.5 Macro IS STM lens was attached to a Canon EOS M3 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.
The full frame at 28mm
Centre sharpness remains high through from f/3.5 to f/11, with f/16 and f/22 being adversely affected by diffraction. The edges aren't nearly as sharp as the centre, with f/5.6 to f/11 producing the sharpest results.
