I have a EOS 1v which I got about half a year ago off Ebay and it has a strange problem. In those 6 months I went through 4 batteries (while shooting maybe 10 films with it). Last time I took it out on Sunday, battery was dead. Thought I must have left it on and pushing the release in the bag, I got a new battery. All worked fine until I took it out of my bag today and battery dead again. This time I'm 100% sure I turned it off. Does anyone have any idea what to try/troubleshoot/etc? Am I doing something horribly wrong by having it in my bag? The lens on it was a MF Oly 50/1.4 with a chipped OM-EOS adapter. Thanks!
