Well fortunately I only have a Hasselblad film camera. Don't think I'll get in to their digital system. I do have a SB-800 and I'm sure I can fire it remotely with either my D2x or D2H, without having to have a flash unit trigger it since I don't always want light coming from the camera. If it's easy, I'm sure its something I'd like to know and try. BTW Samy's is great, when I worked at DC Shoes we purchased many things from there. I actually set up DC's in house studio from their. Bought a Hasselblad 555 system, but used a Leaf digital back with it that was connected to a Mac Tower. Was a few years ago, but really nice system.
