Canon Control Ring Mount Adapter EF-EOS R: attach any EF/EF-S lens to EOS R cameras with full AF, IS, configurable Control Ring, and dust/water resistance.

The **Canon Control Ring Mount Adapter EF-EOS R** is the essential Canon lens accessory for EOS R mirrorless shooters who want to unlock their entire library of EF and EF-S lenses without sacrificing a single feature. Engineered with no optical elements, it preserves the full native image quality of every lens you attach while maintaining complete autofocus and image stabilization performance.

What sets this adapter apart from standard mount converters is its built-in, customizable Control Ring — the same intuitive ring found on Canon’s premium RF-mount lenses — letting you assign and adjust critical exposure settings such as ISO, aperture, and exposure compensation right at your fingertips. Add dust- and water-resistant construction and you have a professional-grade adapter ready for any shooting environment.

### Key features

- **Configurable Control Ring:** Assign ISO, aperture, or exposure compensation to the tactile control ring for fast, intuitive exposure adjustments — just like native RF lenses.

- **Tactile Click Feedback:** The control ring delivers physical feedback as you turn it, so you always know exactly how much adjustment you are making without taking your eye off the viewfinder.

- **Full AF and Image Stabilization Retained:** No compromises — autofocus speed and lens-based optical stabilization operate exactly as they would on a native-mount body.

- **Zero Optical Compromise:** Contains no glass or optical elements, ensuring the original resolving power, contrast, and color rendition of your EF/EF-S lens is fully preserved.
