All in all, the 2 cameras feature different resolutions and different sensor dimensions. The K100D S featuring a larger sensor is going to make getting shallower depth of field easier and the Pentax WS80 will show greater detail due to its extra 4 Megapixels. Greater resolution can also make it easier to crop photos way more aggressively. The more aged K100D S will be behind in sensor tech.
