Quite often, it is difficult to see the contrast between sensor sizes merely by reading through specifications. The image below may offer you a better sense of the sensor dimensions in the D3S and 645Z.

Plainly, the two cameras offer different resolutions and different sensor sizes. The D3S with its tinier sensor will make getting shallower DOF more challenging and the Pentax 645Z will give greater detail with its extra 39MP. Higher resolution can also make it easier to crop shots a little more aggressively. The more aged D3S is going to be disadvantaged when it comes to sensor innovation.
