I bought a used Atik 414ex camera. There are some adapters that came in the box - I'm trying to figure out what one of them is.
See photos. The outer part of this seems to be a standard T/T2 thread (42mm or so) - that fits the Atik camera.
In the 1st photo you can see a few mm of male thread sticking out (toward the camera). That exactly fits a C-mount adapter, so I know what that is. (It's identical to the thread on the end of a C-mount lens.)
What's the inner part? In the photos you can see I'm measuring it. It's about 21.5 to 22 mm diameter (a bit more than you see on the calipers because I'm not measuring the thread depth). What does this fit?
