Learned a weird lesson about lens fungus from a 1950s Kiev camera
Picked up a beat up Kiev 4 at a garage sale last month for $15. Figured it would be a fun project to clean up, maybe get it working. When I opened it up, the lens had this thick web of fungus inside, like someone left it in a damp basement for decades. I almost tossed the whole thing, but an old repair guide I found online mentioned something I never knew. Apparently, some Soviet era lenses used a type of lubricant that actually attracts fungus and holds moisture. That mineral oil they used back then just sits there waiting for spores. I spent two days carefully cleaning the glass with hydrogen peroxide and alcohol, and it actually cleared up better than I expected. The shutter still sticks, but the lens is usable now. Has anyone else run into weird lubricant issues with older cameras?
