Nikon D4s vs Pentax 645D Sensor Comparison

Typically, it is tough to see the difference in sensor sizing merely by going through a spec sheet. The visual here will help offer you a clearer sense of the sensor sizing in the D4s and 645D.

As you can see, both of the cameras enjoy different resolutions and different sensor sizing. The D4s featuring a smaller sensor will make achieving shallower DOF harder and the Pentax 645D will show greater detail having its extra 24MP. Greater resolution can also make it easier to crop pics far more aggressively. The more recent D4s is going to have an edge when it comes to sensor technology.
