Summary: I've been shooting with either on-camera flash or tungsten studio light for over 10 years, and this flash has changed my life. I'm not exaggerating. The power and precision are unbelievable. Using bounce-fill mode (pointing the flash toward the ceiling), I'm able to shoot ad-hoc photos as if they were lit in a studio. Not a $1m studio, mind you, but the subjects look "lit" rather than "flashed".
Summary: I use a few of these when I'm working on a remote job where studio lighting is too cumbersome to lug along. With the 600-ex-rt fitted to the shoe on the camera and 3 of these in a slave setup I usually can get the desired lighting effect I'm looking for. On it's own it's a great flash but as a slave controlled by a canon controller is when it truly shines.
Summary: I have 2 580 EX II's and I wanted some more speedlites for background lighting but didn't want to fork out the $$$ for another 580II. The 430EX II works great and has plenty of power! It's a perfect addition to my speedlte collection.
Became interested in quality cameras to avoid using flash, it's Ironic that this is now my favorite thing to use.

Summary: Length:: 2:53 Mins This is my first video review so please excuse the lack off skill :). The camera was set to 1/80 F1.4 ISO 250 for the pictures taken. The no flash picture was out of focus (could you tell by the delay) so I decided to take three consecutive pictures at the time of posting this to maintain consistency. It was a little darker out but all of the pictures were taken at the same time. Overall I love this flash.
