Adaptador de objetiva Canon EF-EOS R Control Ring Mount Adapter

Connect Canon EF and EF‑S lenses to Canon RF‑mount cameras using the Lens Adapter Canon EF‑EOS R Control Ring Mount Adapter. The adapter preserves autofocus performance and image quality while adding a programmable control ring that lets you adjust settings such as aperture, shutter speed, ISO or exposure compensation directly from the adapter without taking the camera away from your eye. The adapter is weather‑sealed against dust and moisture and has a compact, portable design with a length of 24 mm and a weight of 130 g.

Advantages

The adapter provides full mechanical and electronic compatibility between EF/EF‑S lenses and EOS R cameras, maintaining autofocus and image data transmission. A programmable control ring offers quick, tactile access to commonly adjusted camera parameters. Weather sealing protects against dust and moisture, and the adapter’s compact 24 mm length and 0.13 kg weight make it easy to carry and use on location.

Suitable for

• Photographers who own Canon EF or EF‑S lenses and want to use them on EOS R bodies
