Canon Mount Adapter EF-EOS EF-EOS R 0.71x (4757C001)
Brand: Canon
Color: Black

The Canon Mount Adapter EF-EOS R 0.71x 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.
