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

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. The three adapters have differing features: * 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

When Canon announced its first R-series body, it announced four new RF-mount lenses: * RF 24–105mm F4 L IS USM * RF 28–70mm F2 L USM * RF 50mm F1.2 L USM * RF 35mm F1.8 MACRO IS STM — 0.5× maximum magnification. 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: * RF 85mm F1.2 L USM * RF 85mm F1.2 L USM DS — Same as the above, except includes "defocus smoothing" technology intended to improve

bokeh In photography, bokeh ( or ; ) is the aesthetic quality of the blur produced in out-of-focus parts of an image. Bokeh has also been defined as "the way the lens renders out-of-focus points of light". Differences in lens aberrations and ...

. According to Canon, the effect is similar to that of an apodization filter, but achieved through special lens coatings instead of a filter. * RF 15–35mm F2.8 L IS USM * RF 24–70mm F2.8 L IS USM * RF 24–240mm F4–6.3 IS USM * RF 70–200mm F2.8 L IS USM In 2020, Canon introduced 7 new RF mount lenses: * RF 24–105mm F4–7.1 IS STM * RF 600mm F11 IS STM — fixed-aperture lens * RF 800mm F11 IS STM — fixed-aperture lens * RF 85mm F2 MACRO IS STM — 0.5× maximum magnification * RF 50mm F1.8 STM * RF 70–200mm F4 L IS USM * RF 100–500mm F4.5–7.1 L IS USM In 2021, Canon introduced 7 new RF mount lenses: * RF 100mm F2.8 L MACRO IS USM - 1.4× maximum magnification * RF 400mm F2.8 L IS USM * RF 600mm F4 L IS USM * RF 14–35mm F4 L IS USM * RF 16mm F2.8 STM * RF 100–400mm F5.6–8 IS USM * RF 5.2mm F2.8 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 has introduced seven new RF mount lenses: * RF 1200mm F8 L IS USM * RF 800mm F5.6 L IS USM * RF-S 18-150mm f/3.5-6.3 IS STM * RF-S 18-45mm f/4.5-6.3 IS STM * RF 24mm F1.8 MACRO IS STM * RF 15–30mm F4.5–6.3 IS STM * RF 135mm F1.8 L IS USM RF-mount lenses are not compatible with EF, EF-S or EF-M mount camera bodies.
