• Front side - accepts Arri Bayonet lens
• Rear side - Canon EOS-R (RF) male bayonet mount

Machined from high quality aluminium alloy.

This adapter can be used for zoom lenses in Arri Standard mounts without issues.

Prime lenses with an Arri-S mount can be used as well, but with some issues (you'll need to turn the inner optical block instead of the focusing mount).
