I have a little technical question out of curiousity. To get my Leaf Aptus to synch with the copal shutter I just put the pc sync cable there and it works. The back wakes up fast enough to react on shutter opening thanks to the dalsa sensor I know that, but how does it detect that it closes? I thought the pc sync cable just sent a signal when the shutter opened, not when it closes, right/wrong?
If it does send a signal when it closes, howcome many backs (like Hasselblad) that require wakeup also cannot detect when the shutter closes, but you have to set a fixed shutter speed in the back itself? It seems like incredibly strange design if they just ignore the shutter close signal if there is one, but maybe that really is the case?
