These adapters, developed exclusively for the EOS R system, allow existing EF lenses and their functions to be used with the EOS R series of cameras. They allow EF lenses (including super-telephoto, telephoto, wide-angle, macro, TS-E lenses, etc.) to be mounted on EOS R series cameras. The functions of the lenses, including autofocus, image stabilizer (IS), control operations via the camera’s control dial, and optical corrections, can be utilized with almost no differences.
The Control Ring Mount Adapter EF-EOS R allows users to control settings via the control ring, even with EF lenses. Settings such as aperture and shutter speed can be assigned.
* Some EF lenses do not support certain functions. RF lenses, RF-S lenses, EF-M lenses, and CN-E lenses (EF cinema lenses) are not supported.
