I guess I have two questions.

First, is there any reason to believe using an SB-600 on a non-Nikon film camera (Minolta x-370, or Voigtlander Bessa R2A) would cause any damage to either the camera or the flash? I know old flashes on new cameras can be bad, but as far as I know, a new flash on an old camera is ok, right?

Second, is there any way to set up the flash in some kind of semi-auto mode, or do I have to fall back on using guide number calculations or a flash meter? All I really want to do is bounce the flash off the ceiling, and I'm trying to avoid buying a flash meter.

I'm pretty ignorant about flash photography, so any advice is appreciated. I've used some of the fancy i-TTL stuff with my D70s, but I'm lost when it comes to actually doing it myself.

Thanks,
Paul
