Frustrating .... I was out shooting Tri-X this morning with both my Contax G1 and Canon ... Went through a roll on the Canon first, switched to the G1 and at about frame 16 the roll rewound So I thought maybe I was just crazy, loaded up another roll, and it rewound at frame 3 ..... Got home, loaded an old roll of Fuji color film I had laying around ... walked around the yard .... it shot all 36 exposures fine .... SIGH. Loaded ANOTHER roll of Tri-X ...... rewound at frame 8. 1. No, I'm in no way accidentally hitting the mid-roll rewind button on the bottom 2. All this film was purchased retail from my local shop ... anybody think it could just be wound too tight or something? I mean, it works fine in my Canon's which also have auto-rewind at the end of the roll. I'm pretty frustrated. I wish there was an override for the entire auto rewind situation. TIA for any help and interested to hear if anyone else has ever experienced this problem. PS- Yes, HI .. I am new on this forum (love it) but not new to film or photography. I used to own a G1 years back, so this is my second ... obviously used. I'm kinda of trying to find out if its defective.
