Got the 44.5mm hole punched in the lens board. Now I need the thread specs for the jam nut.
Appears to be a non-standard thread or a not-modern thread.
Anyone know the thread diameter and pitch on a 152mm Ektar in a flach supermatic?
I'd like to get this project going by the end of the summer. Any critics of this lens? Hear it's a keeper but can't prove it yet.
