So my girlfriends parents had a yard sale this past weekend and all the stuff they didn't sell, they were going to give to Goodwill. Well they didn't sell her fathers Sigma SA-1 and I asked them could I have it and they said sure. Well I was playing around with it without any film in it (pressing the shutter release and doing the film advance lever thingy) and it got to "S" on the film counter and the film advance lever is loose, not ratchiting like before. I replaced the battery in it this morning to see if that would help but it hasn't. Somebody helllp!!!!
