colm_timmons Posted March 25, 2003 Share Posted March 25, 2003 I recently took a loan of an additional A12 back with a view to purchasing it to supplement my existing back. It is in great cosmetic shape and seems to have been used sparingly and with care. However, when I am loading film in the usual way it does not stop at frame 1 like my existing back, it continues to wind the film onto the empty reel unhindered. It is older than the back I have been using. Is this a feature of the older backs (serial no. UC) or is it a fault? Regards, CT. Link to comment Share on other sites More sharing options...
russell_britt Posted March 25, 2003 Share Posted March 25, 2003 Is it an A-12 or just a 12. The A-12 stops at frame one, the older 12 has a window in the back so you can see the film numbers and you stop it at 1 and it stops at the other frames.Does it have a window or door on the back? If it does its the older style. Link to comment Share on other sites More sharing options...
colm_timmons Posted March 25, 2003 Author Share Posted March 25, 2003 Russell, it looks identical to my existing back, it has a window on one side that displays the current frame number. Regards, CT Link to comment Share on other sites More sharing options...
q.g._de_bakker Posted March 25, 2003 Share Posted March 25, 2003 Com, The back (UC = 1975, so it is indeed an A12) is at fault. Should be easy and quick to fix. Link to comment Share on other sites More sharing options...
jon_mittelstaedt Posted March 25, 2003 Share Posted March 25, 2003 Sounds like the same problem I just recently had fixed. I was told that it happens when things get kind of gummed up in there. It works fine now. Link to comment Share on other sites More sharing options...
hasselblad technician Posted March 25, 2003 Share Posted March 25, 2003 Colm, The film should stop winding at the first frame in this film back. It is not an uncommon problem, and any competent Hasselblad technician will be able to repair it for you.

colm_timmons Posted March 26, 2003 Author Share Posted March 26, 2003 Thank you all for your responses. I have purchesed the back and have sent it to my nearest Hasselblad Shop for it's repair / service. Regards, CT. Link to comment Share on other sites More sharing options...
Rob F. Posted March 26, 2003 Share Posted March 26, 2003 I have an A12 that does this also. I find that winding very slowly, and counting the number of revolutions, helps me to not wind through the stopping point. It takes 7 revolutions to reach frame 1; if I approach this point very slowly and lightly, it will stop mechanically at frame 1. Otherwise, it will wind right on through. Of course, this is only an emergency procedure; the back does need service when this starts to happen. Link to comment Share on other sites More sharing options...
