I just got a 622 from a friend who was getting rid of her stuff. It came with a couple of CA-1AF adapters and a cable from one adapter to the flash. My camera doesn't let me make any settings with it hooked up, but the flash will fire when I press the shutter. It looks like the pin to adjust the ISO has broken off, but the other adjusters are OK.
Man that thing is bright!
What I'd like to know is if there's anything I can do to make it adjustable from my camera. Would a pocket wizard or anything give more flexibility or control at the camera? Are the CA-1AF adapters good for anything beyond providing a plug to the flash?
