Nikon D5 vs Pentax 645Z Sensor Comparison

More often than not, it's hard to picture the gap in sensor sizing merely by checking out a spec sheet. The visual below might offer you a more clear sense of the sensor measurements in the D5 and 645Z.

As you can see, the 2 cameras posses different resolutions and different sensor sizing. The D5 using its smaller sensor is going to make achieving shallow DOF harder and the Pentax 645Z will provide greater detail because of its extra 30MP. Higher resolution will make it easier to crop photographs somewhat more aggressively. The fresher D5 should have an edge with regard to sensor tech.
