Well, much to yawn inducement of the forum, I posted some test shots that got out from the preproduction Pentax *ist DS. Well, now I have my own to post.

This was my first day out of the house with my new toy, wandering around Roanoke, VA. All of these were taken in "natural" mode (shapening, color saturation turned down for maximum detail), using shutter priority, aperture priority, and manual. I haven't used the presets much, as I am a control freak.
I have the night shots uploaded at full resolution elsewhere but they were taken with a bad lens, setting I regret, and a broken tripod so I think I will save full resolution samples for later - when I have some that do some justice to the camera.
