I went up to Mt. Bonnell on my day off for the specific purpose of taking some video with the K-x.  It was so hot that I was only out there for about half an hour before the camera started to overheat, even when the clips I was taking were under a minute long.  I took that as a sign it was time to leave, but before I did I decided to snag a shot or two with my iPhone and upon reviewing the footage was very impressed with the shots from the phone.  One of them even made the cut.
