Quite often, it can be tough to visualise the difference between sensor sizing simply by checking a spec sheet. The visual here will help provide you a clearer sense of the sensor measurements in the E-M1X and A77 II.

As you can see, the 2 cameras have different resolutions and different sensor sizing. The E-M1X using its tinier sensor will make getting shallower DOF harder and the Sony A77 II will give more detail having an extra 4 Megapixels. Higher resolution can also help you crop shots a bit more aggressively. The younger E-M1X is going to have an edge in sensor tech.
