Conclusion

The Canon EF-M 11-22mm f/4-5.6 IS STM is an impressive ultra-wide-angle zoom that will appeal most to travel and landscape photographers looking for a portable and versatile lens.

The Canon EF-M 11-22mm f/4-5.6 IS STM's build quality is reassuringly good, and it's a great match for the EOS M, where the focal length changes to 18-35mm. Auto-focusing is quiet and pretty quick on the EOS M with the latest firmware, with the ability to instantly manually override it via the focus ring if required proving a nice touch.

Image quality is very good, with sharpness more than satisfactory at both the centre and the edges of the frame even when shooting wide open. Geometric distortion is low for such a wide-angle lens and chromatic aberrations and flare are well controlled, although there's obvious corner shading at the maximum aperture at 11mm.

The Canon EF-M 11-22mm f/4-5.6 IS STM is a surprising addition to the EF-M range, but a very welcome one none-the-less, providing excellent wide-angle coverage at a price that won't break the bank.
