CANON Mount Adapter EF-EOS R 0.71X

Adapt, frame, add brightness and more
The EF-EOS R 0.71x Mount Adapter is an EF-RF mount lens adapter that maintains the original angle of view of a full-frame EF lens when used on the EOS C70. In addition, it increases light transmission to offer an image a brighter spot.
Extending the range of compatible lenses while maintaining their original field of view, the Canon Mount Adapter EF-EOS R 0.71x allows you to attach EF-mount lenses to RF-mount mirrorless and cine cameras. Intended for cameras with Super 35 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 the Super 35 crop factor and increasing maximum aperture performance at one point. . Electrical contacts are also built into the adapter's design and maintain full communication between the camera and lens, as well as supporting metadata transmission and use of Dual Pixel AF with select Canon EF lenses. Additionally, the adapter is designed specifically for the EOS C70 cinema camera and features four screws and a split locking collar to ensure a secure hold.

Maintain Full-Frame Viewing Angle
The adapter offers the same angle of view when using full-frame lenses on the EOS C70's Super 35mm sensor, adapting the focal length by a factor of 0.71x from full-frame to Super 35mm format.

A brighter spot
By reducing the focal length of the lens, the EF-EOS R 0.71x mount adapter increases light transmission, effectively raising the f/point value of a lens. For example, an F2.8 lens approaches F2.0, for low-light photography with lower signal noise.

Superior communication between lens and body
Full communication between EF lenses and the camera body is maintained, with support for Dual Pixel CMOS AF, as well as peripheral illumination and chromatic aberration correction. The adapter also transmits lens information, which is displayed on the screen (support for F-value, focal length, and lens metadata).

Construction without compromise
Designed for reliability and durability, the included locking plates secure the adapter to the body with four screws. Shoot with confidence even with large, heavy lenses.

Lens compatibility
This adapter physically supports working with any Canon EF mount lens, however, select lenses can maintain full support for Dual Pixel autofocus and metadata transmission between the lens and camera, including:
EF 16-35mm f/2.8L IIIUSM
EF 24-70mm f/2.8L II USM
EF 24-105mm f/4L IS II USM
