To sum up, both of the cameras posses different megapixel count and different sensor measurements. The GH3 having a smaller sensor will make shooting shallower DOF more difficult and the Sony A7R will show greater detail using its extra 20MP. Greater resolution will also enable you to crop pics somewhat more aggressively. The older GH3 will be disadvantaged when it comes to sensor technology.
