As you can tell, both cameras have got different megapixels and different sensor sizes. The 645Z having a larger sensor is going to make shooting shallower depth of field less difficult and the Pentax 645Z will provide greater detail using its extra 39 Megapixels. Greater resolution can also allow you to crop pics much more aggressively. The fresher 645Z should have a benefit with regard to sensor tech.
