|Introduction | Canon EF-M 22mm f/2 STM performance | Canon EF-M 22mm f/2 STM mounted on Canon EOS M Versus Nikon Coolpix A Lens | Conclusion|
With a DxOMark score of 21 points the 22mm is a decent performer for a high-speed compact lens with a short focal length. Although it has quite high vignetting at maximum aperture it’s well controlled from f/2.8 onwards and it has reasonably low levels of chromatic aberration. Transmission at 2.3Tstops could be better but it’s not unexpected in a lens of this type. Sharpness is high, though, at 13P-Mpix and it has good edge-to-edge sharpness overall though that applies mainly to aperture settings from f/2.8 onwards.
