The K100D S using its bigger sensor will make achieving shallower depth of field less difficult and the Pentax VS20 will offer greater detail because of its extra 10 Megapixels. Higher resolution will also allow you to crop photographs more aggressively. The older K100D S is going to be behind with regard to sensor innovation.
