Designed specifically with the Canon Cine lenses in mind (works with all Canon EF mount lenses!), the Cine Edition adapters from Fotodiox were built to mimic the breech-lock cine style cameras that those lenses are designed for. The biggest advantage of using an adapter with a breech-lock mounting mechanism is that they have a very solid connection, reduce friction and wear & tear on the lens.

The FUSION technology built into the adapter enables electronic communication, powered by your camera, between mixed lens and camera platforms enabling auto focus, aperture control, image stabilization, EXIF and aperture data to be transmitted to and controlled by the camera and more.

The ND Throttle is a built-in variable neutral density filter that offers 1 to 8 stops of light reduction. This version of the ND Throttle also features a locking thumbscrew on the filter ring to ensure that it is not knocked out of place during shooting or while changing lenses so that every shot will match where it matters in terms of light transmission.

Compatible Canon RF Mount Cameras (Popular models include):
* Canon EOS R, RP, RA, R5, R6

Notes:
* The CINE mount rotates until snug with no defined stopping point or locking catch. Turn until tight, loosen by turning the opposite way. Make sure to tighten sufficiently but do not turn too far or it will fall off as this is how PL-style mounts function.
* Not all Canon EF lenses will perform the same depending on Lens firmware, focusing motors, age of lens and manufacturer. Test lenses before critical shoots.
* For firmware updates and directions, please see the firmware update article for this adapter in the Fotodiox technical support knowledge base.
* All pictures are for illustration purposes only. Actual product may vary slightly due to ongoing improvements in design.
