I've had my new K10D for just under a week now. I have only shot one event with it but that was nearly 500 photos. It was a youth soccer game at the local Y. I suspect my Tamron 70-300 4.0-5.6LD Marco lens is not the best suited for action sports but it did a decent job and I ended up with some keepers.
I took some quick and dirty (literally) product shots of the camera here.
It's going to take some getting used to with the different mode dial settings, but from what I've seen so far I really like it. It has some neat features that I will discuss over the next few weeks.
