Normally, it is very tough to visualize the contrast between sensor dimensions merely by reviewing specifications. The picture underneath will provide you a better sense of the sensor measurements in the E-M10 and A9.

Plainly, each of these cameras feature different resolutions and different sensor dimensions. The E-M10 featuring a tinier sensor is going to make shooting shallower DOF tougher and the Sony A9 will deliver extra detail as a result of its extra 8 Megapixels. Greater resolution can also let you crop photos way more aggressively. The more aged E-M10 is going to be disadvantaged in sensor tech.
