The Viltrox EF-EOS R2 Auto Focus EF to RF Lens Mount Adapter is not an official Canon product, but rather a third-party lens adapter manufactured by companies like Viltrox and SNIPIZ. It allows Canon EF and EF-S lenses to be used on Canon EOS R series mirrorless cameras, which use the RF mount.
Key features of the EF-EOS R2 adapter
The main function of the EF-EOS R2 is to bridge the incompatibility between the EF and RF lens mounts, but it also offers several enhancements:
- Customizable control ring: A defining feature of the R2 version of this adapter is the built-in control ring, which can be programmed to adjust camera settings like aperture, shutter speed, ISO, or exposure compensation. This mimics the function of the control ring on native RF lenses.
- Autofocus and image stabilization support: The adapter has electronic contacts that allow communication between the lens and the camera body. This preserves autofocus, auto-exposure, and the lens’s built-in image stabilization (IS).
- EXIF data transmission: It also allows the camera to read and display the lens information (EXIF data).
- USB port for firmware updates: An integrated USB port allows for firmware updates, which can improve compatibility with new cameras and lenses.
- Durable construction: Manufacturers typically build the adapter from aluminum and copper alloys for enhanced durability.
Compatibility
The adapter is widely compatible with most Canon EOS R system mirrorless cameras, including:
- EOS R, RP, R3, R5, R6, R7, R8
- EOS R50, R100
