Nikon D6 vs Pentax 645Z Sensor Comparison

Normally, it's difficult to envision the difference between sensor sizes only by reading specifications. The image below may provide you a stronger sense of the sensor sizing in the D6 and 645Z.

Plainly, the 2 cameras come with different megapixels and different sensor sizes. The D6 featuring a tinier sensor will make achieving shallower depth of field tougher and the Pentax 645Z will deliver greater detail as a result of its extra 30MP. Higher resolution can also allow you to crop photographs a good deal more aggressively. The newer D6 is going to have an edge with regard to sensor innovation.
