All in all, both the cameras come with different megapixels and different sensor measurements. The E90 having a tinier sensor will make shooting shallower DOF trickier and the Sony RX10 IV will deliver extra detail using its extra 10 Megapixels. Higher resolution will enable you to crop pictures a good deal more aggressively. The older E90 is going to be disadvantaged in sensor tech.
