Focusing ring on 50mm summicron jammed


Recommended Posts

Focusing ring on my collapsible 50mm summicron f/2 lens is all jammed up after I sent it to Focal Point in USA for glass polishing and re-coating. It doesnt even move a bit after push the focusing tab down.

If you have any experience on how to fix this problem please share it with me.


Thank you very much in advance.

Welcome to the forum !!!

The focus helicoid of the old Summicron is indeed a bit delicate, and it was largely based on the design used for the Summitar (the Elmar/Hektor used a simpler construction). But in your specific sutation it seems clear that the lab who made the polishing of the glass didn't make a good work (you do not specify... but I suppose that focus movement was ok when you sent to them your lens) : they MUST take care on the issue. I don't know the lab you quote... but, generally speaking, the labs that are REALLY trustable for maintenance of old Leitz items aren't so many... but this forum is a very trustable source of infos about which are the GOOD labs around the world : see for instance here : http://www.l-camera-forum.com/leica-forum/leica-collectors-historica/133653-repair-specialists.html

Hi Khan - I've had various work done by John van Stelten at Focal Point and based on my experience I would be very surprised if he wouldn't fix it - have you tried contacting him? That would seem the best course of action. Good luck

Why not contact John directly - I have had some work done by him with absolutely no issues. He is one of the very few remaining technicians in the US who will re-polish and re-cement lenses and he does indeed stand behind his work
