I knew I'd screw it up good, but could I wait till I had instructions more detailed than, "Sure you just do this, this and this and bang, you're in business"? Of course not. Okay: Zeiss Ikon Contaflex Super BC (black body), with the dreaded magazine back. Got a desultory lesson from an, er, individual who seemed to know about it, in loading the back ("It's just like a Leica," said individual claimed). So without any further looking into it, I loaded it up and after some fiddling got it to lock on the back. Went out this morning to try and blow through a roll in the ten seconds per day of personal time my job seems to be granting me these days. Yep -- rushing in without a map! Went through, I assumed, said roll, and when I went to rewind, found it was all jammed up and wouldn't rewind. It would continue to "advance" and cock the shutter till the cows came home, though at this point I'm not convinced the film was even advancing. All right, so I figured I'd just sacrifice the roll -- my pictures are always terrible anyway so what the heck -- but the back wouldn't come off. Specifically, the release thingie on the take-up side won't turn to release it. Tried it with the dark slide in, nope; dark slide out, double nope. Same with shutter cocked/uncocked. So by now I'm thinking "big hammer," but I figure I'll just let someone else handle it, but oops! I forgot I live in Cleveland! The only professional repair place in town says their Zeiss specialist DIED LAST FEBRUARY!!! Does anyone have any experience with this device? Is there anywhere on the web where I might find detailed instructions on the magazine back (assuming of course I havn't wrecked the camera)? Am I a big idiot or what? Any and all help appreciated. Thanks.
