RF 85mm F1.2 L USM DS - Same as the above, except includes "defocus smoothing" technology intended to improve bokeh.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 35mm F1.8 MACRO IS STM - 0.5× maximum magnification.When Canon announced its first R-series body, it announced four new RF-mount lenses: Lenses RF50mm F1.2 L USM without lens hood 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. 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.Control Ring Mount Adapter EF-EOS R – the Mount Adapter EF-EOS R with a lens control ring.The three adapters have differing features: The EF-M mount has a flange focal distance of 18 mm.Īn 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 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. In comparison with that mount, the RF mount's inner diameter is the same at 54 mm. ![]() 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.Ĭanon full-frame cameras have used the EF lens mount since 1987. The RF mount allows for the use of Canon EF and EF-S mount lenses using one of three Canon-made lens adapters. In May 2022, Canon announced APS-C EOS R cameras (the EOS R10 and EOS R7) and RF-S lenses designed for these cameras. The RF mount was announced in September 2018. 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. ![]()
