You have a new option if you're looking for a lightweight Canon flash. Despite its small size, the 270EX has a max guide number of 27 using only 2 AA batteries. Probably the biggest upgrade is the rotating flash head that allows for four different bounce shooting positions from 0 to 90 degrees. Of course, there's no room for a screen, so you'll be making your adjustments using your camera's LCD. More photos after the jump.
