Nikon D2X vs Pentax 645D Sensor Comparison

As you can see, both cameras have different megapixels and different sensor dimensions. The D2X with its tinier sensor is going to make getting shallower depth of field harder and the Pentax 645D will offer extra detail using its extra 28 Megapixels. Greater resolution will also help you crop images a bit more aggressively. The more aged D2X is going to be disadvantaged with regard to sensor innovation.
