Olympus E-M1 vs Sony A7c Sensor Comparison
Usually, it is difficult to envision the gap between sensor measurements merely by reading technical specs. The photograph underneath should offer you a more clear sense of the sensor sizes in the E-M1 and A7c.
As you have seen, each of the cameras provide different megapixels and different sensor measurements. The E-M1 using its tinier sensor will make achieving shallower DOF more difficult and the Sony A7c will deliver extra detail using its extra 8MP. Higher resolution will allow you to crop shots more aggressively. The older E-M1 is going to be disadvantaged in sensor tech.
