Yes it will work on a K10D, update your firmware.

Summary: Nice lens, focus is quiet and quick, much better than screw drive. Not the sharpest wide open but most zooms are not. Just stop the lens down a bit. On Pentax cameras this is no need for the optical stabilization so just leave it off. Sigma has removed this on their newer Pentax lens.
Summary: I really like the lens...does great for my need...can't beat it for the price...I have taken a lottttttt of photos with the lens...BUT what I have taken I've been rather impressed...again considering the price I paid for the lens...so yes..
Summary: I'm not a pro by any means, but I am happy with the money I spent on this lens. I'm getting some great shots. I'm sure that some more seasoned users will find fault with the glass quality, etc. And it does seem to be a bit fuzzy around the edges, but it suits my needs for now :)
Summary: images are a little soft, and colors arent as sharp and vivid as my nikkor lens but it has a great zoom and its stabilized! if you cant afford the nikkor zoom lens, definitely take a look at this one
Summary: In my first foray into photography, I decided to take a telephoto lens instead of the kit lens (bought a Nikon D5100 separately), to shoot pictures of people and food (what can I say, I'm -sortof- from the Instagram generation).
Summary: I purchased this a week ago and have taken it out on three shoots already. The first was some action photography of a sport bike race. I took photos using the automatic zoom in the corners and on the strait with the bikes approaching 190mph.
