I picked up a Summaron 35mm f/3.5 at an estate sale — no front or rear caps, just a leather pouch. The focus ring is completely stuck, though the aperture ring moves smoothly and releases the focus lock. I tried a little lighter fluid to loosen things up, but no luck. I’m thinking about trying 99% isopropyl alcohol next, and if that doesn’t work, I’ll send it out for a CLA.
I’d love to hear from anyone who’s dealt with a similar issue on this lens. Did you manage to free the focus ring yourself, or was a professional service the only real fix?
