Comments about Pentax K20D (Body Only) 14.6-megapixel Digital SLR Body:
Bought this as a companion to my K10D. The K20D does extremely well in low light and gives good quality images above ISO1600 (extended range goes to iso6400). Sensor based image stabilization means I can use it with any Pentax lens from my 16mm fisheye to my 400mm screw-mount telephoto. The weather sealed body means you can take it out in the rain, especially if you've got one of the weather sealed DA* lenses.
Worth every penny I spent.
