Excerpt: This was my first Speedlite flash. I found it very capable, but somewhat underpowered. I say capable because there are a number of features that I was very (pleasantly) surprised by that make up somewhat for the flash being underpowered. I think this is a great flash to "get your feet wet", but it seemed a bit pricy for what it delivers.
Pros: Durable, Easy To Use, Lightweight, Masterslave, Versatile, Wireless
Excerpt: I bought a Cannon 60D and realized I needed a flash that was flexible for both recording video and flash photography. Overall, the 320 was made for just that. I like it but I think if I had to do it again I would choose the 400 series.
Excerpt: Was pleased with the ease of use and compatibilty with my T4i, wish there was more manual abilities. Otherwise, what sets this flash apart is the fill video light which is very useful in short video interviews, etc.
Pros: Consistent Output, Durable, Easy To Use, Fast Recycling, Powerful Output
