This adapter allows using modern cameras with T2 mount on Delta/Unitor Bellows.

1. The T2 thread allows a T2 mount to connect the bellows to modern cameras.
2. The small screw fits into a slot in the rear stage of the bellows to restrict the rotation.
3. The 10 mm dimension provides a built-in extension to the adapter so that the projecting grip, pentaprism, etc. of modern cameras can be accommodated.
4. The two components screw together, allowing the mount to rotate without coming off the rear stage of the bellows.

Weight is 33 g.

Made of anodized aluminium.
