Plainly, both of these cameras posses different megapixel count and different sensor measurements. The GH2 with its smaller sensor is going to make getting shallow DOF more difficult and the Pentax 645D will result in greater detail with its extra 24MP. Greater resolution will also allow you to crop pics somewhat more aggressively. The fresher GH2 provides a benefit with regard to sensor innovation.
