Canon Mount Adapter EF-EOS R (Retail Packing)

The Standard Bridge Between Canon's EF and RF Systems

The Canon Mount Adapter EF-EOS R (Retail Packing) allows photographers to use their existing Canon EF and EF-S lenses on Canon's RF-mount mirrorless cameras, built for those transitioning to the EOS R system without wanting to replace their entire lens collection. It maintains full compatibility with autofocus, image stabilization, and electronic aperture control, giving EF and EF-S lenses a genuine second life on RF bodies.

Designed for a Smooth System Transition

This adapter is made for photographers who want to carry their EF lens investment forward into the RF mount. It allows EF and EF-S lenses to function on EOS R-series bodies exactly as they did on EF-mount DSLRs, with no loss of autofocus speed, accuracy, or metering performance, making it a practical bridge for photographers upgrading their camera body while keeping their glass.

Simple, Reliable Construction

Unlike Canon's Control Ring version, this standard adapter keeps things simple, with no additional control ring or customizable functions, just a direct, reliable mechanical and electronic connection between lens and body. It's built with the same optical-quality communication contacts as Canon's other adapters, ensuring no degradation in image quality, autofocus performance, or lens data transmission.

Rugged, Field-Ready Build

The adapter features solid metal construction and a secure locking mechanism, providing a stable, dependable connection between lens and camera body for demanding shooting conditions. Its compact design adds minimal bulk to a kit, making it an easy addition for photographers who want to keep their setup as streamlined as possible while still accessing their existing EF lens collection.
