Arri Bayonet (Arri-B) lens to C-mount camera adapter

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

A lens is held by three set screws. Intermediate flat spring protects a lens mount from damage by screws.

Bayonet lugs position isn't limited, so you can secure a lens at any angle for convenience.

Lenses with Arri-S (Standard) mount can be used as well, but their operation will change since this adapter locks the lens mount so it can't rotate inside as purposed by Arri-S original mount. Zoom lenses with Arri-S mount can be used without issues.

The adapter is machined of high quality aluminium alloyWhy aluminium?.
