I'm curious: will a Canon flash work with a different camera brand? I have a Canon 177A speedlite that, when mounted on the hotshoe of my Minolta HiMatic 7s, fires when I release the shutter (even without a battery in the camera! I'm confused ). My question is: will the shutter sync with the flash? I could just put a roll of film through it, but I reckoned I'd ask before wasting film. Thanks for any opinions on this.
