Usually, its tough to visualize the difference in sensor sizing purely by viewing specifications. The visual here should provide you a stronger sense of the sensor measurements in the E-M5 III and K-70.

Plainly, both the cameras provide different megapixels and different sensor sizing. The E-M5 III with its smaller sensor is going to make getting shallower DOF trickier and the Pentax K-70 will render greater detail using its extra 4 Megapixels. Greater resolution will let you crop pics more aggressively. The newer E-M5 III should have a benefit when it comes to sensor tech.
