To sum up, both of the cameras come with different megapixels and different sensor sizes. The I-10 having a tinier sensor will make achieving shallower DOF more difficult and the Sony RX100 IV will offer more detail having an extra 8MP. Higher resolution can also allow you to crop shots a good deal more aggressively. The more aged I-10 is going to be disadvantaged in sensor innovation.
