[1] The R mount was discontinued in 1964 and replaced with the Canon FL lens mount. [2] Many mirrorless interchangeable-lens cameras are able to use Canon R lenses via an adapter.

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 last non-EOS based SLR camera produced by Canon, the Canon T90 of 1986, is widely regarded as the template for the EOS line of camera bodies, although the T90 employed the older FD lens-mount standard. For a detailed list of EOS Film and digital SLR cameras, see Canon EOS.

The EOS R features a 30.3 megapixel CMOS sensor, an OLED viewfinder and an articulating LCD touchscreen. Autofocus uses dual-pixel technology, and "Eye Detection AF" automatically focuses on human faces ...
The distance is only 0.5 mm larger than the Nikon F-mount, which is not sufficient to make a workable adapter, however, at least one Nikon camera has been modified with a Leica R bayonet mount to take R lenses, [citation needed] and at least two manufacturers make replacement mounts, allowing many Leica R lenses to be used directly on various ...
The Canon PowerShot Pro1 is the first in the Canon PowerShot family of point-and-shoot cameras to have an L-designated zoom lens ranging from 7.2 to 50.8 mm, equal to 28 to 200 mm in 35mm equivalent focal length. Its maximum aperture changes from f / 2.4 to f / 3.5, with focus driven by an ultrasonic motor.
