Pentax 645Z vs Pentax K-1 II Sensor Comparison
Typically, it's difficult to imagine the difference in sensor sizing only by seeing specifications. The photograph here may offer you a much better sense of the sensor dimensions in the 645Z and K-1 II.
Plainly, the 2 cameras have different megapixel count and different sensor sizing. The 645Z with its bigger sensor is going to make getting shallower depth of field less difficult and the Pentax 645Z will produce extra detail using its extra 15 Megapixels. Higher resolution can also make it easier to crop shots a bit more aggressively. The older 645Z will be disadvantaged in sensor technology.
