Canon Control Ring Mount Adapter EF-EOS R
Developed to extend the range of compatible lenses for Canon EOS R full-frame mirrorless digital cameras, the Control Ring Mount Adapter EF-EOS R allows you to attach any EF or EF-S lens to the EOS R camera. Aside from being able to enjoy the full capabilities of any EF or EF-S lens, this compact and lightweight adapter comes with the same configurable Control Ring found on the new RF-mount lenses. This dedicated lens ring allows intuitive in-lens adjustments of the aperture, ISO, and other exposure settings. It is also capable of retaining the mounted lens’ full AF and image stabilization capabilities while maintaining its original optical quality, so it won’t interfere with camera and lens operations.

The Control Ring Mount Adapter EF-EOS R adds a control ring like those
found on RF lenses, providing the same level of control to your EF and EF-S
lenses and supporting the same setting configuration regardless of lens.
