Plainly, the two cameras come with different resolutions and different sensor dimensions. The GH1 using its larger sensor will make achieving shallow depth of field easier and the Panasonic GH1 will render greater detail with its extra 2MP. Greater resolution will also make it easier to crop photos a good deal more aggressively. The newer GH1 will have an advantage in sensor tech.
