Canon EF-EOS R 0.71x Mount Adapter

The Canon Mount Adapter EF-EOS R 0.71x is designed to bridge the gap between Canon's extensive range of EF lenses and the EOS C70's RF mount. By adapting the focal length by a factor of 0.71x, it maintains the original angle of view of full-frame EF lenses when used on the Super 35mm sensor of the EOS C70. This means your wide-angle lenses stay wide, and your telephotos retain their reach.

One of the standout features of this adapter is its ability to increase light transmission, effectively making your lens one stop brighter. For instance, an f/2.8 lens becomes approximately f/2.0, enhancing performance in low-light situations and allowing for greater depth-of-field control.

Built with precision, the adapter ensures full communication between the lens and camera body. This includes support for Dual Pixel CMOS AF, as well as peripheral illumination and chromatic aberration correction. Lens metadata, such as f-number and focal length, is also transmitted and displayed on the camera screen, ensuring seamless integration into your workflow.
