Canon Control Ring Mount Adapter EF-EOS R

Control Ring Mount Adapter EF-EOS R offers the same lens mount conversion as Mount Adapter EF-EOS R, allowing EF-S and EF lenses to be used with the Canon EOS R, and also adds a lens control ring.

Customisable functionality

The Lens Control Ring can be programmed via the camera’s menu to adjust various settings such as aperture, shutter speed, ISO sensitivity and exposure compensation.

Tactile, intuitive handling

It’s easy to find the Lens Control Ring without taking the camera away from your eye. Gentle clicks give a tactile feedback in thirds or halves of a stop.
