Panasonic S1R vs Pentax 645Z Sensor Comparison
More often than not, it can be tough to see the gap between sensor dimensions merely by looking at technical specs. The pic below should offer you a greater sense of the sensor sizing in the S1R and 645Z.
As you can tell, both of the cameras offer different megapixel count and different sensor dimensions. The S1R featuring a tinier sensor will make shooting shallower depth of field tougher and the Pentax 645Z will give you more detail due to its extra 4MP. Greater resolution can also allow you to crop photos a little more aggressively. The younger S1R will have an advantage with regard to sensor technology.
