The RF mount is Canon’s second attempt at a mirrorless mount, this time with support for full-frame sensors. The RF mount was announced in 2018; it is a bayonet mount with three tabs, with a throat diameter of 54mm and a focal flange distance of 20mm. Support for APS-C sensors, designated as RF-S, was introduced in 2022 and utilises Canon’s standard 1.6\u00d7 crop factor. The RF mount uses 12 pins for fully digital communication between the camera and the lens; there are no mechanical linkages. Full compatibility with EF and EF-S signalling is retained, meaning simple adapters with pass-through connections are sufficient to maintain all adapted lens functions.<\/p>\n\n\n\n
EF-M mount lenses cannot be adapted due to shorter focal flange distances.<\/p>\n\n\n\n

As of January 2024, some makers have announced that existing lenses are available, indicating that deals with Canon have been made.<\/p>\n\n\n\n Voigtl\u00e4nder, Zeiss, and Laowa lenses for the RF mount have electronic contacts but are manual focus.<\/p>\n\n\n\n RF-S lenses are made for APS-C sensors. Canon released a total of seven RF-S lenses.<\/p>\n\n\n\n All announced Sigma and Tamron APS-C lenses for the RF-S mount were released by the end of November 2024.<\/p>\n\n\n\nCanon RF lenses<\/h2>\n\n\n\n
