Canon EF 20mm f/2.8 USM Lens Review
The Canon EF 20mm f/2.8 USM is an ultra wide angle prime lens for the EF (full frame) mount. It can also be used on APS-C bodies such as the Canon Rebel series and the XX-D bodies such as the 80D, 70D and will also mount on the 7D bodies as well. On these APS-C cameras the field of view will be similar to a 36mm lens on a full frame body.
