Query: Canon Speedlite 430EX II

Obviously, goes well with the EOS cameras. I've only had it for less than a week, so I'm still learning how to use the large number of features. These features provide a lot of flexibility, especially when coupled with all of the different camera modes. Recycle time and battery consumption also seem to be good, again given the short amount of time I've been using it (but a lot of test shots). I've gotten good results with flash coverage as far as 30' (which may not be its limit, but it's as much as I've used so far). The low light focus assist is a great benefit in speeding up the camera's focus under those conditions. It's not a small unit, but not unwieldy, either. The rotate/bounce really helps to soften the sometimes harsh flash light. This seems to be a great addition to my EOS camera.
