Canon EF-M 22mm lens
The Canon EF-M 22mm f/2 STM is an interchangeable wide-angle lens announced by Canon on July 23, 2012. It was not available from Canon USA until the 27th of August 2015, but it was available as part of a kit with the EOS M in 2012.
As a pancake lens, it is the physically shortest Canon lens available on the EF-M mount. Its 22mm focal length has the same field of view on an EOS M-series camera as a 35mm lens on a full-frame camera.
