Hi newbie here
Currently I'm considering to get myself a flash (realised it's pretty impt for indoor shots)
i read that there are a few models such as 430EX, 550EX, 580EX, etc (pls list if there are any more)
May i know what's the difference between these models?
I was thinking of getting a 580EX but I'm not a pro or a freelancer, just getting started in photography as an interest, thought that it would be an overkill to get such an expensive end. :P
