Use this adapter to convert your full frame EF lenses into RF Super35 format AND gain a stop of exposure (via a max aperture change) in the process. This technical wizardry allows you to regain the field of view of your wide lenses by 0.71x on a crop sensor, while at the same time giving you a slightly more full frame "look" in regards to depth of field and bokeh.

It passes through all electrical connections between the EF lens and the RF body, including autofocus functions as well as metadata information such as aperture, focus distance, and focal length.

We highly recommend renting this while using EF lenses on the C70 Cinema camera.
