Clearly, the 2 cameras enjoy different megapixel count and different sensor sizes. The 645Z featuring a larger sensor is going to make getting shallow DOF simpler and the Pentax 645Z will offer you greater detail having its extra 39 Megapixels. Greater resolution will also let you crop images far more aggressively. The more recent 645Z should have an advantage in sensor tech.
