I don't suppose I'm the only person with some lenses minus lenscaps. My lenses are mostly older, uncoated or single coated. I put them in ziplok bags and then into pockets in my backpack, thinking the plastic cannot scratch the glass. But a friend suggested that while the uncoated glass is probably safe, the older softer coating on Ektars might be vulnerable. So I've been improvising caps from film cans, jug tops etc. Some fit, and some almost fit but need a bit of tape to snug. But I wonder if the gaffer's tape glue will outgas en route to its final white powdery condition, depositing haze on the lens, and make matters worse than no cap at all.
Perhaps cut some ventilation holes?
I wonder if storage in ziplok bags or if plain plastic (no tape) caps present the same haze hazard?
