Sharpness at 22mm
The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Canon EF-M 22mm f/2 STM lens was attached to a Canon EOS M 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 22mm
Centre sharpness remains high through from f2.8 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/2.8 to f/8 producing the sharpest results.
