Olympus E-M1X vs Sony A7R II Sensor Comparison
Usually, it is difficult to picture the contrast between sensor measurements purely by looking at technical specs. The graphic below will help give you a far better sense of the sensor sizing in the E-M1X and A7R II.
As you have seen, both of the cameras come with different megapixel count and different sensor measurements. The E-M1X having a tinier sensor is going to make getting shallower DOF harder and the Sony A7R II will give you more detail because of its extra 22MP. Higher resolution will help you crop pictures a good deal more aggressively. The fresher E-M1X should have an edge in sensor tech.
