The details
At a glance: EF to RF mount adapter with a programmable control ring - full EF-S/EF compatibility on R-series bodies.
About this lens
The Canon Control Ring Mount Adapter EF-EOS R is Canon's premium adapter for using EF and EF-S lenses on Canon's RF mirrorless bodies. Adds a programmable control ring that can be assigned to aperture, ISO, shutter speed or exposure compensation - a clever way to bring EF glass forward without compromise.

Best for
The best way to use existing Canon EF and EF-S lenses on an RF-mount mirrorless body. All electronic communication, autofocus and IS are preserved at full speed. The programmable control ring adds a physical control surface matching RF-native lenses. Fully compatible with all R-series bodies (R, RP, R3, R5, R6, R7, R8, R10, R50, etc.).
Frequently asked questions
What can the control ring do?
The ring can be assigned via the camera menu to control aperture, shutter speed, ISO, or exposure compensation. Clicked or declicked (custom service) for stills or video use.
How is this different from the standard EF-EOS R adapter?
The standard adapter is a plain passive mount converter - no control ring. The Control Ring version adds a physical control ring that brings EF lenses closer to RF-native handling.
Will EF-S lenses work on a full-frame R-series body with this adapter?
Yes. The body automatically switches to a cropped APS-C imaging area when an EF-S lens is detected.
Why buy from Bass & Bligh
Bought from a real shop, not a warehouse.
Dispatched on the Monday… great service
Ordered a Panasonic four thirds lens dispatched on the Monday after purchase and delivered on the following Tuesday great service. Tried on the camera and initial thoughts are wow pin sharp and clear photos. Thank you
George P.Ordered a lens onlineA proper little treasure trove
3rd time I've been to this shop to treat myself to some new kit. Always very friendly and knowledgeable. Fairly priced too. I would highly recommend a visit if your nearby and looking for camera gear. I'd say if they don't have what your looking for, it's probably not possible to find anywhere. It's a proper little treasure trove.
Philip B.Third visit to the shopBrilliant advice with awesome customer service
Sure you can buy online and possibly save a few pounds.. but if you require and appreciate knowledge and brilliant advice with awesome customer service then it's a no brainer...This is a real camera shop like it used to be back int day..
