• Frot side - Canon EF-M male bayonet mount
• Rear side - Arri B female mount

Machined of high quality aluminium alloy.

This adapter allows using Arri B (bayonet mount) lenses on cameras with Canon EF-M mount.

Infinity focus is provided.

Flat metal tension spring protects the lens mount from damage by holding screws.

Arri S lenses can be used as well, but primes will change their behavior to less convenient due to securing the mount instead of allowing its proper rotation for focusing. Zoom lenses in Arri S mount can be used without any problems.
