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 A pancake lens is colloquial term for a flat, thin camera lens assembly (short barrel). The majority are a prime lens of normal or slightly wider angle of view. Some are zoom lenses. Motivation Pancake lenses are primarily valued for providi ..., 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.

Pancake Lens
A pancake lens is colloquial term for a flat, thin camera lens assembly (short barrel). The majority are a prime lens of normal or slightly wider angle of view. Some are zoom lenses. Motivation Pancake lenses are primarily valued for providing quality optics in a compact package. The resulting camera and lens assembly may even be small enough to be pocketable, a design feature which is usually impractical with conventional SLR bodies and lens assemblies. Pancake lenses can be very short and flat because they do not need large amounts of optical correction, i.e. extra lens elements. The problem arises when such lenses have too short a focal length to fit in front of the retractable mirrors used in reflex cameras. In such a situation, a pancake lens focuses in front of, rather than on, the focal plane (film or light sensor) of the camera. This has necessitated the design of retrofocus lenses that refocus the image farther back, which is why such lenses are longer and bulkier ...

Canon EF-M Lens Mount
The Canon EF-M lens mount, introduced in 2012, is a derivative of the Canon EF lens mount designed for use with the Canon EOS M mirrorless interchangeable-lens camera. The EF-M lens mount is one of Canon's two new systems for mirrorless cameras, the other being the RF mount. The M system has an 18 mm flange focal distance (compared to 20 mm for RF and 44 mm for EF and EF-S) and a 47 mm throat diameter (compared to 54 mm for EF, EF-S, and RF). As it is designed for use with an APS-C-sized image sensor, it features the same crop factor In digital photography, the crop factor, format factor, or focal length multiplier of an image sensor format is the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital ca ... (of roughly 1.6) as the existing EF-S lens mount. The M system is somewhat limited as Canon has issued relatively few native lenses, listed below. There is a lack of native ...
