Clearly, the two cameras posses different resolutions and different sensor measurements. The E-M10 having a tinier sensor will make achieving shallower DOF trickier and the Sony A7c will offer you more detail having an extra 8 Megapixels. Greater resolution will allow you to crop pics somewhat more aggressively. The older E-M10 is going to be disadvantaged in sensor technology.
