Canon RF lens mount
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]

The RF mount allows for the use of Canon EF and EF-S mount lenses using one of three Canon-made lens adapters.
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.[1] 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.[8] The three adapters have differing features:[9]
- Mount Adapter EF-EOS R
- Control Ring Mount Adapter EF-EOS R – the Mount Adapter EF-EOS R with a lens control ring
- Drop-In Filter Mount Adapter EF-EOS R – the Mount Adapter EF-EOS R with the ability to use drop-in filters, either a variable neutral density (V-ND) filter or circular polarising (C-PL) filter, and a clear (CL) filter, to be released in 2019
The EOS R is a 30 megapixel (6720 × 4480) full-frame camera. If an EF-EOS R Mount Adapter is used with it to mount an EF-S lens, the camera will function as an 11.6 megapixel (4176 × 2784) crop camera.
Lenses
At the time Canon announced its first R-series body, it announced four new RF-mount lenses:[10]
- Canon RF 24–105 mm f/4 L IS USM
- Canon RF 28–70 mm f/2 L USM
- Canon RF 50 mm f/1.2 L USM
- Canon RF 35 mm f/1.8 IS STM Macro — 0.5× maximum magnification.[11]
In conjunction with the February 2019 announcement of the entry-level full-frame EOS RP, Canon announced that six additional lenses would be released by the end of that year, although it did not indicate release dates for any of them:[12]
- Canon RF 85 mm f/1.2L USM
- Canon RF 85 mm f/1.2L USM DS — Same as the above, except includes "defocus smoothing" technology intended to improve bokeh. According to Canon, the effect is similar to that of an apodization filter, but achieved through special lens coatings instead of a filter.[13]
- Canon RF 24–70 mm f/2.8L IS USM
- Canon RF 15–35 mm f/2.8L IS USM
- Canon RF 70–200 mm f/2.8L IS USM
- Canon RF 24–240 mm f/4–6.3 IS USM
In 2020, Canon has announced 7 new RF mount lenses:
- Canon RF 24–105 mm f/4–7.1 IS STM
- Canon RF 100–500 mm f/4.5–7.1L IS USM
- Canon RF 600 mm f/11 IS STM — fixed-aperture lens
- Canon RF 800 mm f/11 IS STM — fixed-aperture lens
- Canon RF 85 mm f/2 Macro IS STM — 0.5× maximum magnification
- Canon RF 50 mm f/1.8 STM
- Canon RF 70–200 mm f/4L IS USM
RF-mount lenses are not compatible with EF, EF-S or EF-M mount camera bodies.
