I have a Canon Speedlite 199a that I never used from my 35mm days and a Fuji 6x7 camera. I've only used available light for my photography in the past, but having an upcoming stuff that I'd like to use flash with, can anyone tell me if I'll be able to cover the 6x7 format with what I'm presuming is a flash made for 35mm cameras only. Sorry if it's a dumb question! I hunted around and couldn't find out if a different flash unit is needed for the larger format or if all are created equal. Thanks in advance.
