Pentax 645D vs Pentax 645Z Sensor Comparison
Often, its difficult to see the contrast in sensor sizing simply by seeing a spec sheet. The visual here might give you a better sense of the sensor dimensions in the 645D and 645Z.
Clearly, both of the cameras posses the exact same sensor measurements but not the same resolution. You can expect to see the Pentax 645Z to provide greater detail using its extra 11 Megapixels. Greater resolution can also allow you to crop photos somewhat more aggressively. The older 645D will be disadvantaged with regard to sensor technology.
