As long as the cells remain the same distance apart (and threads match), it should work fine. You likely won't have a calibrated aperture scale, however.
If the threads don't match, or if you want to get an aperture scale engraved to match your lens, you're looking to send some stuff to S.K. Grimes...
As the DB-aperture resp. DB-mount is designed to accept lenses in barrels made in dimensions for classic shutters, the re-transplantation should work fine,
It is a matter of logic. Or am I overlooking something?
Ok. On the auction site, I saw a Fujinon 360mm cells mounted on a db for I think 500 or bucks. Or so. It got me thinking because I have four other lenses in copal 3, can I not unscrew the 360mm set and screw onto a copal 3 I already have??
