Plainly, both cameras come with different resolutions and different sensor sizing. The K100D S due to its bigger sensor will make achieving shallower DOF less difficult and the Sony RX10 II will render more detail due to its extra 14 Megapixels. Higher resolution can also allow you to crop pictures a good deal more aggressively. The older K100D S will be behind when it comes to sensor innovation.
