Sinaron 90mm f4.5 gender?

Hi All, I have rescently aquired a s/h Sinaron 90mm f4.5 w/a lens that is mounted in a DB mount. The front part of the lens appears conventional (thread wise) but the rear part instead of having a male thread seems to have a female thread. As I want to mount the lens in a copal or compur shutter, is there adaptor?

Thanks in advance Dave

Not all DB mount lenses can be fitted into a normal shutter, sounds like the Sinaron is probably an f4.5 90mm Grandagon. My Grandagon & Super Angulon 90mm's rear cells fit direct to the rear thread of a Copal/Compur 0.

I think you're probably out of luck with the Sinaron, but I'd suggest you ask Teamwork, (Foley St, London), tomorrow they may be able to advise you.

Thanks Ian....That was good and bad news..........Cheers Dave
