  • Very compact and light
  • Bright f/2.0
  • Handy 22mm focal length for general usage
  • 7 rounded aperture blades
  • Fulltime manual focus
  • Metal lens mount
  • Front element doe not rotates during focusing


  • A bit slow focus speed stepping motor compared to existing USM variants
  • Uncommon 43mm filter diameter
  • Small and expensive lens hood
  • No optical image stabilization
  • Not weather sealed, front element simply moves out/in during focusing operation


This is in my opinion a must have fixed lens that everybody should have for their Canon EOS-M cameras.

This 22mm covers about the same visual field of an fullframe 35mm lens. Its fast f/2 aperture helps in low light condition or for providing some amount of background blur.

The only dranwback is the relativly slow stepping motor that moves the focusing the internals. Not a problem in most situations but I prefer the quick USM variants.

The image quality this small prime delivers is very good for the prize.
