hi, i disassembled my pentacon 200 mm f4 prime lens to lubricate it and can't put it back can you please do a video since you did one optik gorlitz 200mm prime aperture.
Thank you very much for your prompt response. Indeed, I believe mine is a preset lens since it only has an aperture ring and no auto function. Your videos help a lot of people who don’t have any knowledge about vintage photographic lenses like me😂😂😂 Reassembling that helicoid means a lot to us who own that same lens. I did a research on the net and found nothing. So thank you again for kindness and for sharing your knowledge.
