My dad was a photographer when he was in college. He has some film gear laying around from the 70s, and on a whim, I decided to try his flash (Minolta Auto 132X) on my camera. It fires! The downside is that I haven't been able to adjust any of the settings (flash compensation on the camera doesn't do anything), and I've turned the dial on the back and it doesn't seem to do anything (although I don't really understand it). The only setting seems to be REALLY BRIGHT. It may help out in some situations, but I'm still eying an SB-400.
