To sum up, both cameras have different resolutions and different sensor sizes. The E-M10 III using its tinier sensor is going to make getting shallow DOF harder and the Pentax K-70 will resolve greater detail because of its extra 8 Megapixels. Greater resolution will enable you to crop photos a bit more aggressively. The more modern E-M10 III should have an edge in sensor tech.
