Hello

Slowly building out my SInar F2 and sourced a db shutter and some lenses. Some of these lenses are on older style boards and some on the more modern style. Both work great and the auto aperture and stop down works a treat.

I have a couple of lenses I'd like to put in a db shutter ( seems everyone wants to go the other way!).

If my db lens has a 150mm lens in it can I do a direct swap with any other 150mm lens give or take? (flange distance may differ slightly)

If I buy a copal 0 lens db lens board is there a way to set it for the 47mm focal length. A google seems all old websites are dead and no real clear instructions Ive found so far

Thank you
