Canon Mount Adapter EF-EOS R
The Canon Mount Adapter EF-EOS R is the essential bridge for photographers transitioning to the EOS R mirrorless system. This lightweight and compact adapter allows you to seamlessly attach any EF or EF-S mount lens to an EOS R-series body. By maintaining a completely native connection between the lens and the camera, it ensures that your existing library of glass performs exactly as intended on the latest mirrorless technology.
Seamless Integration and Performance
Full Functional Retainment: This adapter supports complete electronic communication between the lens and camera. You retain full use of high-speed autofocus, metadata (EXIF) transmission, and lens-based image stabilization.
Zero Optical Compromise: Designed without any internal glass elements, the adapter acts as a precise mechanical spacer. This ensures that the original optical quality, sharpness, and character of your EF lenses are preserved perfectly.
EF-S Lens Support: When an EF-S lens is attached, the EOS R camera automatically detects the lens and switches to a cropped shooting mode to match the APS-C image circle.
Built for Professional Use
Weather-Sealed Design: To match the durability of professional L-series lenses and EOS R-series bodies, the adapter is dust- and water-resistant. This allows you to continue shooting with confidence in challenging environments and inclement weather.
Rugged Construction: Featuring metal mounts on both the camera and lens sides, the adapter is built to provide a secure, wobble-free connection even when using long telephoto lenses.
Compact Form Factor: Its sleek, unobtrusive design ensures that your setup remains balanced and portable, making it easy to keep as a permanent fixture in your gear bag.
