As you can tell, both of the cameras feature different megapixel count and different sensor measurements. The GX-20 using its smaller sensor is going to make shooting shallower DOF more difficult and the Sony A7 will show more detail because of its extra 9MP. Greater resolution will also enable you to crop pics way more aggressively. The older GX-20 will be disadvantaged with regard to sensor technology.
