In many cases, it is hard to imagine the gap between sensor sizes only by reading through technical specs. The picture here might provide you a far better sense of the sensor dimensions in the E-M10 and A6400.

As you can tell, the 2 cameras enjoy different resolutions and different sensor sizes. The E-M10 because of its tinier sensor is going to make achieving shallow DOF more difficult and the Sony A6400 will give extra detail as a result of its extra 8 Megapixels. Higher resolution will also make it easier to crop shots far more aggressively. The more aged E-M10 is going to be behind when it comes to sensor innovation.
