These two screws came from my zenitar 16mm fisheye. They're tiny, I've put them next to a coin to give you an idea of the size. Problem is they're both broken and I cant find replacements anywhere. Since Monday I have looked at Jaycar, Bunnings, JB HiFi, all new & used camera stores I know, camera repair centres, 2 jewellers and 3 opticians. The accident happened as I was trying to calibrate the lens for infinity focus. No drama, as long as I can find some screws somewhere. Any ideas please?
