As you have seen, the two cameras have different megapixels and different sensor sizing. The GH2 featuring a bigger sensor is going to make achieving shallower DOF less difficult and the Panasonic GH2 will offer you greater detail as a result of its extra 2MP. Higher resolution will help you crop shots a bit more aggressively. The older GH2 is going to be disadvantaged with regard to sensor tech.
