Attach Canon EF-mount lenses to your RF-mount camera while adding corrective filters with this Aureole Drop-In Filter Mount Adapter Ring from Benro. Create your own combination of Aureole lens filters with the separately available filter holders in order to achieve the cinematic look you desire. The adapter can support filter use with more difficult lenses like ultra-wide-angle or fisheye.
The adapter ring supports electronic communication between your lens and camera so you can continue to use your autofocus while shooting. A built-in base on the ring features an Arca-type compatible mount and single 1/4"-20 thread for integration into the tripod system of your choice.
