As you have seen, both of those cameras offer different megapixel count and different sensor dimensions. The 645Z using its larger sensor is going to make achieving shallow DOF simpler and the Pentax 645Z will produce more detail using its extra 15 Megapixels. Greater resolution will make it easier to crop pics a little more aggressively. The more aged 645Z will be behind with regard to sensor technology.
