Hi, I've managed to jam my SL66. Don't think i did anything wrong, the last wind was complete, but none the less the mirror has locked up, the shutter release doesn't do anything and the winding mechanism is locked as if the shutter was wound. Second time its happened, last time it went to Brian Mickleboro who got it back running nicely, but he's off on holiday at for the next few weeks, so willing to give things a go myself. Has anybody got any suggestions to get it back operational? Leaves a bit of a bitter taste it happening a second time, i bought this to replace a Zenith 80 for German reliability, but never mind - its done now. A second body isn't going to be cheap.
