hi all. i have a canon 400d. a friend who has an old film pentax slr has offered to lend me his flash gun.

this is part of the email from my friend.

"the 2 flashguns I've got are for a Pentax SFX camera, one is a quite neat compact static one, the bigger one has an adjustable/manoeuvrable head where you can bounce the flash up or down etc."

would this work on my 400d until i can afford to get a canon 430ex myself?

thanks in advance.
