Often, it's hard to imagine the contrast in sensor measurements just by viewing technical specs. The visual underneath might provide you a far better sense of the sensor sizing in the Fujifilm S3 Pro and 645D.

As you have seen, the 2 cameras posses different megapixels and different sensor measurements. The Fujifilm S3 Pro because of its smaller sensor is going to make getting shallower DOF more difficult and the Pentax 645D will provide you with extra detail due to its extra 34 Megapixels. Greater resolution will allow you to crop pics somewhat more aggressively. The older Fujifilm S3 Pro will be behind when it comes to sensor innovation.
