Hey i just bought a sigma EF 610 DG SUPER external flash to go with my nikon d5100.ive never used an external flash before and i'm still familiarising myself with it but i think so far ive managed to understand its basic functions when used for still photography.i was wondering though is it possibly to use my flash as an open source of light during a video shoot? or are these only capable of making instantaneous flashes?
I have the feeling it most probably does not do what i just asked but im just hoping, it would help me a lot if it does.
>>> Can i use my slr's external wireless flash during video?
