Canon EF-EOS R 0.71x Mount Adapter

OVERVIEW

The Canon Mount Adapter EF-EOS R 0.71x enables the attachment of EF-mount lenses to RF-mount cine and mirrorless cameras, extending the selection of compatible lenses while keeping their original field of view. With an optical system to increase the effective angle of view by 0.71x, reduce the effects of a full-frame to Super 35 crop factor, and improve maximum aperture performance by one stop, this adapter, designed for cameras with a Super 35 sensor size, also has an additional benefit of increasing the effective angle of view. The design of the adapter also includes electric connections that preserve complete communication between the camera and lens, permit metadata transmission, and enable the operation of Dual Pixel AF with specific Canon EF lenses. This adapter has been specifically designed for the EOS C70 cinema camera and features four screws and a split locking collar to ensure a secure attachment.

Lens Compatibility

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:

• EF 16-35mm f/2.8L III USM
• EF 24-70mm f/2.8L II USM
• EF 24-105mm f/4L IS II USM
