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.
The "RF" retroactively stands for "Re-Imagined Focus".[9]

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.[10] The three adapters have differing features:[11]
- 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, released in 2019.
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.

When Canon announced its first R-series body, it announced four new RF-mount lenses:[12]
- RF 24–105mm f/4 L IS USM
- RF 28–70mm f/2 L USM
- RF 35mm f/1.8 MACRO IS STM — 0.5× maximum magnification.[13]
- RF 50mm f/1.2 L USM
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:[14]
- RF 85mm f/1.2 L USM
- RF 85mm f/1.2 L 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.[15]
- RF 24–240mm f/4–6.3 IS USM
- RF 15–35mm f/2.8 L IS USM
- RF 24–70mm f/2.8 L IS USM
- RF 70–200mm f/2.8 L IS USM
In 2020, Canon introduced seven new RF mount lenses:
- RF 24–105mm f/4–7.1 IS STM
- RF 85mm f/2 MACRO IS STM — 0.5× maximum magnification
- RF 100–500mm f/4.5–7.1 L IS USM
- RF 600mm f/11 IS STM — fixed-aperture lens
- RF 800mm f/11 IS STM — fixed-aperture lens
- RF 50mm f/1.8 STM
- RF 70–200mm f/4 L IS USM
In 2021, Canon introduced seven new RF mount lenses:
- RF 100mm f/2.8 L MACRO IS USM - 1.4× maximum magnification
- RF 400mm f/2.8 L IS USM
- RF 600mm f/4 L IS USM
- RF 14–35mm f/4 L IS USM
- RF 16mm f/2.8 STM
- RF 100–400mm f/5.6–8 IS USM
- RF 5.2mm f/2.8 L Dual Fisheye
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:
- RF 800mm f/5.6 L IS USM
- RF 1200mm f/8 L IS USM
- RF-S 18–45mm f/4.5–6.3 IS STM
- RF-S 18-150mm f/3.5–6.3 IS STM
- RF 15–30mm f/4.5–6.3 IS STM
- RF 24mm f/1.8 MACRO IS STM - 0.5×maximum magnification
- RF 135mm f/1.8 L IS USM
In 2023, Canon introduced eight new RF mount lenses:
- RF 24–50mm f/4.5–6.3 IS STM
- RF-S 55–210mm f/5.0–7.1 IS STM
- RF 100–300mm f/2.8 L IS USM
- RF 28mm f/2.8 STM
- RF 10–20mm f/4 L IS STM
- RF-S 10–18mm f/4.5–6.3 IS STM[16][17]
- RF 24–105mm f/2.8 L IS USM Z[18][19]
- RF 200–800mm f/6.3–9 IS USM[20][21]
In 2024, Canon has introduced seven new RF mount lenses:
- RF 35mm f/1.4 L VCM
- RF-S 3.9mm f/3.5 STM Dual Fisheye
- RF 28-70mm f/2.8 IS STM
- RF 70-200mm f/2.8L IS USM Z
- RF 24mm f/1.4L VCM
- RF 50mm f/1.4L VCM
- RF-S 7.8mm f/4 STM Dual
As of May 2025,[update] Canon has introduced four new RF mount lenses:
- RF 16-28mm f/2.8 IS STM
- RF 20mm f/1.4 L VCM
- RF-S 14-30mm f/4-6.3 IS STM PZ
- RF 75-300mm f/4-5.6
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×.
