Pentax K7 review @ DigitalCameraReview.com

The Pentax K7 is the best Dslr released by Pentax so far, and one of the best cameras of this year. Voted as the best camera of 2009 by many,  now it also grabs the editor's choice award at DCR:   "For me, the only control that required me to retrain my brain was the mode dial. Pentax added a locking pin to the mode dial so you have to press a center button to change the shooting mode. This is great since you cannot accidentally change the mode dial, but it's something new for long-time Pentaxians. Once you get used to the new layout, however, you may quickly appreciate that the K-7 seems to have every control you need in the perfect location. The arrangement is definitely similar enough that those seeking an upgrade to their older Pentax cameras won't have much to learn." Link
