I managed to come across my mom's Pentax MG a few days ago. I've always been interested in shooting film so I picked up some low-end film and batteries today. The camera batteries are working properly, however I can't get the shutter to fire. Earlier I couldn't get the wind lever to work properly, but realized it was because I hadn't properly pushed the rewind crank back into place. I'm having trouble with the lever again, but can't seem to figure out why this time. Any ideas on why the shutter isn't working, or lever isn't working? I've been reading the manual but can't seem to find an answer.
