Sometimes, it is very difficult to picture the difference in sensor measurements simply by going through technical specs. The graphic underneath may offer you a much better sense of the sensor sizes in the E-M10 III and a5000.

As you can tell, each of the cameras have got different resolutions and different sensor measurements. The E-M10 III using its smaller sensor is going to make achieving shallower depth of field harder and the Sony a5000 will provide extra detail using its extra 4 Megapixels. Greater resolution will make it easier to crop images much more aggressively. The newer E-M10 III provides an advantage when it comes to sensor innovation.
