My workhorse camera has been a 35mm film Canon EOS650, about 20 years old. I haven't a huge investment in lenses, but do have the standard 50mm, 180mm, 35-70mm zoom, and 170-500mm (pretty crappy) zoom, all autofocus but from 3rd party manufacturers. Last week it started doing strange things; part of the last roll of film was intermittently blank. It seems to record the picture, but then advance the film a random number of frames. I replaced the battery, but still seems to behave about the same. I'm thinking since it has worked so well up to this point, that the repair shop is the first step. Anyone see anything like this before? Eventually I'll 'prolly go digital, but really don't want to spring for the Canon D-60 (to use the lenses) right now.

Well Id say if its twenty years old it needs to retire to a nice warm place, the bottom of your sock draw would be nice. You could then remember the good times, when men where men and a camera took real film, every time you pulled your socks on. Sorry to be no help at all :O)

LOL! Hey! I'm over twenty years old. Can I retire to the sock drawer too? [You could be right.]

Dude, take that poor thing to the repair shop!! If my camera played up, I could never stop using it... but then dude, your camera is like 2 years older than me, and even Im quite battered by now... could be a dilemma... =) Hope you get it fixed mate xXxXx

I think I need to clean out my sock drawer... hmmm... LOL (*

I wouldn't retire it to the sock drawer yet....find out what's up with it at the repair shop and if repair costs are prohibitive than you can consider retirement.
