Negative Positive
Title: A difference of night and day.
Review: I struggled for a while trying to decide between this flash and the 430EX II. In the end I decided to purchase the 580EX II and what a difference it has made to my shooting. It will drastically change your shots. It's easy to use in ETTL and just compensate up and down and bouncing.If you are trying to decide if you should buy a flash, get one. If you maybe want to get a flash or new glass, get the flash first.
