As you can tell, both of the cameras feature different megapixels and different sensor dimensions. The E-M10 II with its tinier sensor is going to make achieving shallower depth of field more challenging and the Sony A7 II will give you more detail with its extra 8MP. Greater resolution can also make it easier to crop images way more aggressively. The more modern E-M10 II provides a benefit when it comes to sensor tech.
