I'll jump in a throw a little love to the K10D. I'm a film shooter foremost, but last fall I purchased a second-hand K10D and 18-55 lens in hopes my wife would join me in my SRL fun. She had been using a couple digital point and shoots, a Pentax H-90 and an Olympus. The camera arrived with the 18-55mm kit lens and I also picked up a 50-200mm lens to cover a broader focal length.
As it turns out, my wife didn't really care much for the SLR world, so I've decided to use the K10D myself. I'm still getting acustomed to using the camera, but so far, I like the results.
Here are some samples - all using the DA 50-200mm and right out of the camera...
cheers,
Fred
