medinfoto Posted August 6, 2020 Share #1 Posted August 6, 2020 Advertisement (gone after registration) Hello! I recently acquired a pile of gear, including some R equipment. One piece I got is a nice looking Summicron-R 35, appears to be two cam version if I understand correctly. However, the front is a little loose, to the point where you can twist it back/forth a couple of millimeters and wiggle it a tiny bit. Enough that it seems like something's not quite right. Is there a diagram available somewhere that'll show the construction? There's a ring you can loosen with a spanner wrench but it appears to get stuck against the front ring/bezel after a turn or two so I imagine that one needs to come off. However it's recessed so do you make some sticky (rubber?) tool to unscrew it? And does anyone have any suggestions as to what might be wrong with the lens? It takes nice pictures, the optics are clean as can be, and the aperture oil free, so would like to make it "perfect" again if possible!

I will have to acquire a set since I'm getting back into collecting vintage gear and a lot of it needs a little love. Thanks! Quote Link to post Share on other sites More sharing options...
Dreamplace Posted August 12, 2020 Share #4 Posted August 12, 2020 I recently bought a Summicron-R 35 2-cam and mine also has this wobbly front. Could this be a weakness in this type of lens? Image quality does not seem to suffer: I tested on a full-frame digital Canon camera and the images are fine; better in fact than what I get from brand new 35mm prime and high-end zoom lenses. Since the wobbly front does not seem to impact image quality I'm considering just to leave it as is. But if it would be simple and easy to fix I might want to do that. Medinfoto, could you please inform us about your endeavour to try fixing this? Quote Link to post Share on other sites More sharing options...
