Canon Mount Adapter EF - EOS R, Compatible with EOS R and EOS RP
Description:
Similar to the Mount Adapter EF-EOS R, the Control Ring Mount Adapter EF-EOS R lets you expand your lens compatibility when using the EOS R camera, but with an added control ring for additional customization.

It even comes with a clicking mechanism that delivers easily perceptible feedback, which can be removed for a fee to provide more silent operation if preferred. Featuring a matching design and resilient, dust- and water-resistant construction, the Control Ring Mount Adapter EF-EOS R is a no-compromise way to incorporate your EF and EF-S lenses into the EOS R system.

Features:
- Mount Adapter Allows EF/EF-S Lens Compatibility with the EOS R Camera.

There was a problem filtering reviews right now. Please try again later.
Of note, if you have the older R or RP cameras, or the new R7 or R10 APS-C cameras, then the ring is a bit more useful, since they lack the same amount of controls the more expensive cameras have (only 2 adjustment dials). So if you have one of those cameras, or possibly a future release that also lacks additional dial, it might be worth the additional cost. Or if you just want the additional dial that is fine too. It can be programed to use functions other than ISO and EV.
