Excerpt: I've owned this flash for about a year. It works well and has been durable enough. It's good for P-TTL while mounted on the camera, and it works well as a bounce flash. I've also found it useful as a hair light and fill light while doing portrait work.
Pros: Power, value
Cons: Cheezy hot shoe, Few manual controls, no sync port or slave
Excerpt: After much researching of flash units I decided to purchase this Sigma unit for £107 on Amazon UK. First thing you notice when opening the box is just how big this unit is, it looks even bigger when attached to the tiny K-r.
Summary: I bought one of these flash guns for a previous DSLR, and when I recently upgraded my system to the Nikon D300s, I opted to buy the same flash gun. I read the reviews and the Sigma rated highly. I like the simplicity of use and the price was good. I don't use flash a lot so I wanted a gun that was easy to use and gave good results. The Sigma fitted my needs. [...
Pros: Durable, Great Features, Lightweight, Simple Controls
