Hi guys, I'm looking for a flash for my 7D. I've always been an outdoors shooter, but i'm wanting to get a flash for the times i'm photographing at night, or just low light situations. I know NOTHING about flash, i've never tried to really learn about it, but i'm about to get into it, and i'm looking for opinions! I've heard good things about the Nissin Di866, that it's very similar to the 580EX II - but would that be too full on for someone new to it all? the 580EXII is too exxy for my price range at this point in time, so if the nissin is too hardcore, would I be best off going for the 430 EX II? Sorry if this has been posted about a million times ;p. TIA!
