I have acquired a Regula variant 740-2 flashgun which appears to be Canon dedicated. It seems to be a very sophisticated model, with a turning bounce head and a small fill in flash on the body. Of course there is no manual.
Can anyone point me in the direction of a manual please. I plan to try it anyway with my G7 and an AE1, but I have never tried to use quite so complex a flash unit before and would like to learn how to use it to best advantage.
