DO IT!My Zorki 4K is mint, I should put a roll in it this spring. Same lens.
Yeah, so I've read. It's the downside of the Zeiss Sonnar design, but everyone says it should be very good with stopped apertures. I'll see what I can do to clean it as soon as I find a screwdriver small enough for some of those screwsThe Jupiter-8 is a sweet-looking lens, and very lightweight too. I had one on my Olympus E-P1 a while ago.
It was very easy to take apart; the one I had, though, wasn't very sharp wide open.
Made this for that :If you're having pre/post focus issues to fix with that dock, you do know how to measure the error so you can input it into the firmware fixer, right?
