The R mount was used on Canon's first single lens reflex (SLR) camera. The mount employed a "breech lock" system to attach the lens to the camera body. [1] The R mount was discontinued in 1964 and replaced with the Canon FL lens mount. [2] Many mirrorless interchangeable-lens cameras are able to use Canon R lenses via an adapter.
In 2022, Canon introduced the first RF-S lenses (RF-S 18-150mm and the RF-S 18-45mm) for APS-C Sensors, together with the R7 and R10 camera bodies with the first built in APS-C Sensor in the R-System.

The Canon PowerShot Pro1 is the first in the Canon PowerShot family of point-and-shoot cameras to have an L-designated zoom lens ranging from 7.2 to 50.8 mm, equal to 28 to 200 mm in 35mm equivalent focal length. Its maximum aperture changes from f / 2.4 to f / 3.5, with focus driven by an ultrasonic motor.
Canon New FD lens mounting surface.. The FD lens mount is a breech-lock mount, which is a variation of the common triple-flanged bayonet attachment. The advantage of the breech-lock over the bayonet is that neither the contact surfaces between the body and lens, nor the signalling mechanisms, rotate against each other when the lens is mounted.

It retains the same sensor and lens as its predecessor. The main improvement is the new DIGIC 7 Processor. In fact the G7 X Mark II is the first Canon camera to use this new chip. [8]
