Sometimes, it is very hard to picture the difference in sensor measurements just by checking out technical specs. The visual here will give you a better sense of the sensor dimensions in the GH2 and K-7.

As you have seen, each of the cameras come with different megapixel count and different sensor measurements. The GH2 using its smaller sensor is going to make achieving shallow DOF more difficult and the Panasonic GH2 will provide extra detail with its extra 1 Megapixels. Higher resolution will also make it easier to crop photographs a good deal more aggressively. The more modern GH2 provides an advantage when it comes to sensor technology.
