In many cases, it can be difficult to picture the difference between sensor dimensions merely by reading technical specs. The pic here should provide you a much better sense of the sensor measurements in the E-M5 and A7c.

As you have seen, both the cameras offer different megapixel count and different sensor dimensions. The E-M5 due to its tinier sensor is going to make shooting shallower depth of field more challenging and the Sony A7c will deliver greater detail as a result of its extra 8 Megapixels. Greater resolution will also make it easier to crop images a little more aggressively. The more aged E-M5 is going to be disadvantaged with regard to sensor tech.
