Canon RF lens mount explained

Mount Name:Canon RF mount
Type:bayonet
Inner Diameter:54 mm[1]
Flange:20 mm[2]

The Canon RF lens mount is an interchangeable-lens mount developed by Canon for its full-frame mirrorless interchangeable-lens cameras, and featured first by the EOS R, followed by the EOS RP.[3] [4] [5] The RF mount was announced in September 2018.[6] [7] In May 2022, Canon announced APS-C EOS R cameras (the EOS R10 and EOS R7) and RF-S lenses designed for these cameras.[8]

The RF mount allows for the use of Canon EF and EF-S mount lenses using one of three Canon-made lens adapters. When an RF-S or EF-S lens is attached, however, the camera will only function as an APS-C camera, not a full-frame camera.

Details

Canon full-frame cameras have used the EF lens mount since 1987. In comparison with that mount, the RF mount's inner diameter is the same at 54 mm. The RF mount's flange focal distance at 20 mm is much shorter than that of the Canon EF and EF-S mounts at 44 mm. The EF-M mount has a flange focal distance of 18 mm.

An EF-EOS R lens adapter enables Canon EF, EF-S, TS-E and MP-E lenses to be used on cameras that have the RF mount.[9] The three adapters have differing features:[10]

If an EF-EOS R Mount Adapter is used to mount an EF-S lens, the image will have to be cropped by 1.6x due to the smaller image circle on EF-S lenses.

Lenses

When Canon announced its first R-series body, it announced four new RF-mount lenses:[11]

In conjunction with the February 2019 announcement of the entry-level full-frame EOS RP, Canon announced six additional lenses would be released by the end of that year, although it did not indicate release dates for any of them:[13]

In 2020, Canon introduced seven new RF mount lenses:

In 2021, Canon introduced seven new RF mount lenses:

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.

In 2022, Canon introduced seven new RF mount lenses:

In 2022, Canon introduced seven new RF mount lenses:

Canon has introduced eight new RF mount lenses:

RF-mount lenses are not compatible with EF, EF-S or EF-M mount camera bodies. RF-S lenses can be used on full-frame RF cameras. However, the image will be cropped by 1.6×.
