Canon EF-EOS R adapter with control ring

The Canon Control Ring Mount Adapter EF-EOS R lets photographers use existing EF and EF-S lenses on Canon EOS R series cameras. A built-in control ring adds the same tactile adjustment found on native RF lenses. Metal mounts on both sides provide a secure connection. The adapter is dust- and water-resistant for reliable outdoor use.

Customisable control ring for aperture shutter

The adapter’s defining feature is its programmable control ring that can adjust aperture, shutter speed or ISO without taking your eye from the viewfinder. This brings RF-lens handling to the entire EF and EF-S lineup. No optical elements are included so image quality depends solely on the attached lens.

Ideal for EOS R owners

Photographers who already own Canon EF or EF-S lenses and want RF-style control-ring operation on an EOS R body will benefit most. Shooters who need autofocus with non-Canon mount lenses or who require a pure mechanical adapter without electronic contacts should consider other options.

Questions about this item

What mount standard does the adapter use and what does it connect?

It bridges the Canon EF/EF-S lens mount to the RF mount on EOS R series cameras, preserving full electronic communication and autofocus.
