I have a 210mm Rodenstock Macro Sironar N, mounted on a Sinar DB lens board. I use it with my Sinar camera and Sinar shutter.
If I wanted to put it into a Copal shutter, which size would it take ? I doesn't fit into any of my Copal 1 shutters.
I use some of my lenses in both a Copal shutter, and Sinar DB board, depending on which camera I am using. I would like to do the same with the Macro Sironar.
