To sum up, each of these cameras posses different megapixel count and different sensor sizes. The PEN-F featuring a smaller sensor will make achieving shallow DOF more challenging and the Sony A77 will produce greater detail as a result of its extra 4 Megapixels. Greater resolution will also allow you to crop pics somewhat more aggressively. The more modern PEN-F will have an edge when it comes to sensor innovation.
