This adapter allows using Arri-B (bayonet) lenses on C-mount cameras
A lens is held by three screws and an Intermediate flat spring protects the 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 may 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 made of anodized durable aluminium alloy.
May not work with some Arri standard mount lenses that are barrel focus type.
