A good camera, but an old one. Take a look at the newer K-7 instead. Here's what we had to say about the K10 when it was released back in September 2006:
The Pentax K10D Digital SLR takes extra steps to ensure that you get clean, blur-free photos. The CCD-shifting shake reduction compensates for hand movements and other jitters, while the 10D's intriguing dust reduction system shakes off debris that may collect on the CCD (which is specially coated to resist dust), ensuring clear and crisp photos with no obstructions.
