To sum up, both the cameras have different megapixels and different sensor sizing. The E-M5 having a tinier sensor is going to make achieving shallower depth of field more difficult and the Sony A7 IV will offer extra detail using its extra 17 Megapixels. Higher resolution will also help you crop photographs a bit more aggressively. The older E-M5 is going to be behind when it comes to sensor technology.
