Hi all, I have a old Canon EOS 1N RS I know nothing about this camera. It is in very nice condition. I put batteries in it and it did fire up. I put it in bulb mode and with the back open the shutter will not stay open. I'm thinking the shutter is wore out. The shutter does click and does go into fast mode. Also I don't see the film gear moving. I'm I missing something here? Does the camera want to see film loaded into it? Any info is appreciated. Anybody need this camera for parts? Tom
