Sigma EF-610 DG ST Electronic Flash for Canon Digital SLR Cameras – Review:

POWERFUL AND SIMPLE!

This is a great flash for beginners and pros that are using this on camera. As a professional photographer who primarily uses my flashes off camera I need a bit more flexibility than I did when I first started using this flash. The only negative thing I can find about this flash is that outside of the P-TTL mode, it only has two settings, High and Low. However, for anyone who is simply going to attach this to their camera’s shoe mount this is perfect! P-TTL (auto adjusted flash) works great with my Pentax KX, my K10 and my K5. Since these cameras are at opposite ends of the Pentax line, I’m sure it will work for any of the Pentax models just fine. You can see how I have used it some at my site. [...]
