Canon EF Lens to RF-Mount 0.71x Adapter

The Canon EF-EOS R 0.71x Mount Adapter allows adapting 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.
