Adapters with 41.6mm bore
Adapters with 41.6mm bore.
Main purpose of these adapters is mounting size #1 shutters (Compur #1, Copal #1, Copal Press #1, Prontor #1) to a camera.
Take note that you will need a corresponding retaining ring with M39x0.75 female thread. If your shutter does not have its native ring, you can buy one from us.
