Canon EF-M 22mm f2.0 STM lens review: compact prime with high image qualityBy Kevin Carter - Wednesday September 11 2013 Lens Review
As the equivalent field of view to a 35mm f2.0, this high-speed, compact “pancake’ type lens is an appealing option for the EOS M system user. Read on to find out how well this prime performs in our labs.
The EF-M 22mm f/2.0 STM is a moderately wide-angle fixed focal length lens with the equivalent field of view to that of a 35mm lens and is an attractive option for reportage, street and landscape photography. As with others in the EF-M range it adopts the firm’s new linear stepper motor technology for discreet refocusing using both CD and PD AF during video-capture. It also features slim aluminum barrel measuring just 23.7mm long with a full-time manual focus collar and yet still finds room for a relatively complex construction with 7 elements (one with an aspherical surface) in 6 groups, while focusing to just 15cm and weighing as little as 105g. It has a 55mm filter thread and is available now at $229.
