Canon EF-EOS R 0.71x EF to RF Mount Adapter for Canon EOS C70 (4757C001). An EF to RF adapter designed to enable users to use the broad range of Canon EF lenses on the EOS C70 camera, whilst maintaining the same Full Frame angle of view. Ideal for film and documentary makers, it complements the EOS C70 perfectly for users of EF lenses. Adapt the frame, add brightness, and more. The Mount Adapter EF-EOS R 0.71X is an EF to RF Mount Lens Adapter that maintains the original angle of view of a full-frame EF lens when used on the EOS C70. It also increases the light transmission, to offer a one-stop brighter image.

The MOUNT ADAPTER EF-EOS R 0.71X is an EF to RF Mount Lens Adapter that maintains the original angle of view of a full-frame EF lens when used on the EOS C70. It also increases the light transmission, to offer a one-stop brighter image.

The MOUNT ADAPTER EF-EOS R 0.71X is an EF to RF mount adapter for using the wide range of full frame Canon EF lenses on the EOS C70. Maintain full frame angle of view. The adapter gives the same angle of view when utilising full frame lenses on the Super 35mm sensor of the EOS C70, by adapting the focal length by a factor of 0.71x from full frame format to Super 35mm format.

By reducing the focal length of the lens, MOUNT ADAPTER EF – EOS R 0.71X increases light transmission, effectively increasing the f/stop value of a lens. For example, an F2.8 lens becomes approximately F2.0, for low – light shooting and lower signal noise.

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 in formation from the lens, and is displayed on screen (F value, focal length and lens metadata are supported).

Designed for reliability and durability, the included locking plates secure the adaptor to the body with four screws. Shoot with confidence even when using large and heavy lenses *with supported lenses.
