Should work (but please get conformation from other people as well). The most important thing is that when swapping shutters that the overall length of the shutter/lens combination DOES NOT change (there is a bit more to it, oa the distance from the inside glass elements to the aperture). The lens threads of a Prontor, Compur or Copal O should be identical AFIK (probably there are exceptions). If Dan Fromm does not respond try to PM him, he is very knowledgeable (as Ian is too..;-)..)

Good luck,

Cor

anyway the lens is usable 100% if i know which speeds aren't correct. i can compensate my speeds and use bulb until i fix the lens. maybe i'll find a good shutter and change it at some point. the lens is for portraits anyway so i might not use the slower speeds that much (especially when i get a 135mm for landscapes)

thank you for your time.
