To sum up, both the cameras posses different megapixel count and different sensor sizes. The DP2s featuring a smaller sensor is going to make shooting shallower DOF more difficult and the Sony A7c will produce greater detail as a result of its extra 19 Megapixels. Higher resolution will also enable you to crop photographs somewhat more aggressively. The more aged DP2s will be disadvantaged with regard to sensor innovation.
