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 Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 31.15 mm field d ...-sized image sensor, it features the same crop factor (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 nativ ...

Canon EF Lens Mount
The EF lens mount is the standard lens mount on the Canon EOS family of SLR film and digital cameras. EF stands for "Electro-Focus": automatic focusing on EF lenses is handled by a dedicated electric motor built into the lens. Mechanically, it is a Bayonet mount, bayonet-style mount, and all communication between camera and lens takes place through electrical contacts; there are no mechanical levers or plungers. The mount was first introduced in 1987. Canon claims to have produced its 100-millionth EF-series interchangeable lens on 22 April 2014. History The EF mount replaces its predecessor, the Canon FD, FD mount. The standard autofocus lens mounting technology of the time used a motor in the camera body to drive the mechanics of the focus helicoid in the lens by using a transfer lever. The key innovation of the EF series was to use a motor inside the lens itself for focusing. This allowed for autofocusing lenses which did not require mechanical levers in the mount mechanis ...
