I also found pretty good service manuals here: http://www.canonfd.com/choose.htm with troubleshooting info that says for uneven exposure, clean MG3, which is the solenoid that holds shutter 2 open until it's time to shut it. However I don't know how it could or should be cleaned. I took the bottom cover off and everything seems to be pretty much in order. If there is a problem it must be that shutter 2 sometimes doesn't shut by itself properly. As far as I can tell it's spring-loaded shut and MG3 holds it open, but if MG3 was dirty I don't see how that would cause uneven exposure anyway, just over or under-exposure. I have tried cycling the camera tons of times without film, and I can't seem to duplicate the shutter lagging, or detect any other problem. Maybe I will shoot another roll and see if it fixed itself. Perhaps it just needed used a bit to get things loosened up, after sitting for so long. |
