In many cases, it's hard to visualise the difference between sensor measurements simply by reading specifications. The photograph below will help offer you a stronger sense of the sensor dimensions in the E-P3 and RX10 III.

Plainly, both the cameras have got different megapixels and different sensor measurements. The E-P3 because of its larger sensor will make shooting shallower depth of field less difficult and the Sony RX10 III will offer you extra detail as a result of its extra 8 Megapixels. Greater resolution can also help you crop images much more aggressively. The older E-P3 is going to be disadvantaged with regard to sensor innovation.
