Normally, its tough to picture the difference in sensor sizing only by checking out specifications. The graphic here will help give you a clearer sense of the sensor sizing in the E-M5 III and NEX-7.

To sum up, each of the cameras posses different resolutions and different sensor sizing. The E-M5 III due to its smaller sensor is going to make shooting shallower depth of field more difficult and the Sony NEX-7 will produce greater detail due to its extra 4MP. Higher resolution can also make it easier to crop shots somewhat more aggressively. The younger E-M5 III provides an edge in sensor innovation.
