This is not a full scientific review, but mearly my own opinions based on using this flash gun for about a month, mainly for events photography.
In general I'm really pleased with the 320ex, there are some nice little features on it, however there are also some draw backs, as you'd expect from a bit of kit that trys to do so much for such a low price.
Things I like about it...
I really like the fact that it has a
LED light for video on it, this is really quite a useful feature and was one of the main things that drew me to the 320ex. The light works well on subjects that are fairly close to the camera, ie a person within 5-10 feet. Obviously its not going to light a whole room, but thats not really what its meant for either.
