peter_hoang1 Posted November 9, 2007 Share Posted November 9, 2007 Hello all, i just purchased a xenotar 150mm 2.8 lens and i would like to mount it on a shutter. the lens elements fit into my compur #2 shutter but that has my Dagor in it. so i am looking for another #2 shutter.. i looked at Sk grimes's web site for more infor about these shutters and they came in 6 irregular sizes, and they dont make them anymore. on the schneider optics website, it stated that the shutter size is, "II 5/2+3" whatever that means... my best bet is to buy a lens on ebay with a compur 2 shutter. does anyome know which lenses to look out for? or have a compur 2 shutter laying aroud for sale? thanks in advance for your help!!! -peter Link to comment Share on other sites More sharing options...
dave_s Posted November 9, 2007 Share Posted November 9, 2007 Measure it carefully, and consult with either Flutot ($$) or Grimes ($$$$). Link to comment Share on other sites More sharing options...
sheldonnalos Posted November 9, 2007 Share Posted November 9, 2007 I think the Schneider 165mm Angulon and the 240mm Convertible Symmar both came in Compur 2 shutters. Look at the historical lens data on the Schneider website, it has very precise shutter information on all those lenses. Link to comment Share on other sites More sharing options...
lauren_macintosh Posted November 10, 2007 Share Posted November 10, 2007 You would be better off to E-mail Carol at Flutot camera repair, and ask her , if you sent the shutter to her for her to match a shutter to it : Link to comment Share on other sites More sharing options...
georges_giralt Posted November 10, 2007 Share Posted November 10, 2007 Hi ! I've seen such lens fitted into a bigger shutter with two reducing rings to reduce the size to the correct thread. IMHO, you would have more facility finding someone able to do this job than finding a size II in good working condition. Even when they were made, they were scarce. I _do_ second the Flutot advice.

jason_greenberg_motamedi Posted November 14, 2007 Share Posted November 14, 2007 Peter, To find the correct no. 2 shutter follow Sheldon's advice: you need a 240mm Symmar convertible. Make sure NOT to buy the Symmar-S or any other flavor but plain old Symmar. I never tried a 165mm Angulon, but according the Schneider website it should work. As an important aside, in the 1970s Compur stopped making (or Schneider stopped ordering) the special Compur II shutter, and all 240mm Symmars and 150mm Xenotars were fitted with adapters so they would screw into a Copal no. 3 shutters. So, if you can find a later convertible Symmar in a Copal 3, you can remove the cells, unscrew the adapters (not an easy task, you may need a machinist to help), and fit them to your Xenotar and the Copal 3.

jim_galli4 Posted November 14, 2007 Share Posted November 14, 2007 As Schneider's designation intimates there were different Compur #2. 240 / 420 Convertible Symmar is correct info. Don't get the 180 Xenar f4.5 in Compur 2, it is a larger throat. Also don't get a non-Schneider Kreuznach lens in a Compur 2 as cell spacing was different with different mfr's and it was pre standardization era for shutters. Incidentally when you do get the correct shutter the early G-Claron 305mm Dagor type will also fit if you find one in a barrel cheap. Link to comment Share on other sites More sharing options...
chauncey_walden Posted November 14, 2007 Share Posted November 14, 2007 Yes, my Dagor-type 305mm G-Claron shares a shutter with a 165mm Angulon. Link to comment Share on other sites More sharing options...
