Hi everyone, Let me start by apologizing, because I'm sure this is a common question, but from my searches, I cannot find a simple answer (perhaps there isn't one?). I have a 47mm 5.6 schneider from 1970 in a Synchro Compur #00 shutter, and the leaf shutter is sticky at all speeds. It'll fire, but there's no continuity every time I fire it at one speed. I'm wondering if I need to do the lighter fluid thing (or is that not a good idea?) or just re-lubricate it, or what? Many thanks in advance!
