As you can see, both of those cameras posses different megapixels and different sensor dimensions. The DP1s using its smaller sensor is going to make shooting shallower DOF trickier and the Sony A7R III will produce greater detail using its extra 37 Megapixels. Greater resolution will allow you to crop pics somewhat more aggressively. The more aged DP1s will be disadvantaged with regard to sensor technology.
