short answer: yes - at least in the really basic way: set flash sync speed on the camera body
This is the answer i was looking for, thanks. With this iso and film speed are set, so its only worrying about aperture. I shot a whole roll in the snow with a flash on the A1 guessing the aperture and it all came out fine so i would rate myself to be competent enough.
I understand the benefits of bouncing but I'll try a small flash for now just to see how I get on with it. Wycameras have a T20 for a tenner which seems to be one of the smallest
