Extending the range of compatible lenses while maintaining their original field of view, the Canon EF-EOS R 0.71x Mount Adapter permits attaching EF-mount lenses to RF-mount cine and mirrorless cameras. Intended for cameras featuring a Super35 sensor size, this adapter also incorporates an optical system to increase the effective angle of view by 0.71x, reducing the effects of a full-frame to Super35 crop factor and increasing the maximum aperture performance by one stop. Electric contacts are also incorporated into the adapter's design and maintain full communication between the camera and lens, as well as support metadata transmission and use of Dual Pixel AF with select Canon EF lenses. The adapter directly attaches to RF-mount camera bodies, and four screws and a split locking collar are included for a more secure attachment.
This adapter physically supports working with any Canon EF-mount lens; however, select lenses can maintain full Dual Pixel autofocus support and metadata transmission between the lens and camera, including:
The adapter mounts like any other adapter, however, if you are running heavier lenses it can also be attached via four screws to the body of the C70. If you are going to be swapping between RF and EF lenses frequently you probably wouldn’t want to screw in the EF-EOS R 0.71x mount.

The Canon EF-EOS R 0.71x Mount Adapter is a camera accessory that allows you to use Canon EF and EF-S lenses on Canon EOS R cameras with a 0.71x magnification factor. It essentially bridges the compatibility between the two lens mounts, allowing for a wider range of lens options for EOS R users.
The 0.71x magnification factor reduces the focal length of your lens, resulting in a wider field of view and decreased image magnification. This can be beneficial for landscape or architectural photography, as well as for creating a more cinematic look in videos. Keep in mind that the exact magnification factor may vary slightly depending on the specific lens used.
The Canon EF-EOS R 0.71x Mount Adapter is designed to maintain the image quality of your lens when used on an EOS R camera. The optics of the adapter are specifically designed to ensure minimal distortion or loss of quality. Users have reported little to no difference in image quality when using the adapter.
The adapter is compatible with all EF and EF-S lenses, with a few exceptions. Some lenses may not be fully compatible, such as those with a large protruding rear element. It is recommended to check with Canon or test the lens on the adapter before using it.
When using the adapter, all lens features, including autofocus, are retained. However, some lens-specific functions, such as stabilization or aperture control, may not be supported. Check the lens compatibility with the adapter to determine which features are available.
No, the Canon EF-EOS R 0.71x Mount Adapter is specifically designed for use with Canon EOS R cameras and cannot be used with other camera brands or models. Attempting to do so may result in compatibility issues and potentially damage the camera or lens.
Yes, the Canon EF-EOS R 0.71x Mount Adapter comes with a limited one-year warranty from Canon. This covers any technical or manufacturing faults with the adapter. Extended warranties may also be available for purchase.
Attaching the adapter is as simple as aligning the red dots on the adapter and the lens, and then twisting the adapter clockwise until it clicks into place. To detach, press the release button on the side of the adapter while twisting it counterclockwise. Be sure to hold onto both the adapter and lens when attaching or detaching to prevent any potential damage from dropping.
To ensure optimal performance and compatibility, it is recommended to first attach the adapter to the camera and then attach the lens. Additionally, it is important to keep the adapter and lens connectors clean and free of any dirt or debris.
Yes, the adapter allows for quick and easy switching between EF and EF-S lenses, making it a convenient accessory for users with multiple lenses. However, be sure to power off the camera before attaching or detaching the adapter to prevent any potential damage.
