As you can see, each of the cameras offer different megapixels and different sensor sizing. The 645D because of its larger sensor will make getting shallow DOF less difficult and the Pentax 645D will give more detail having its extra 22MP. Greater resolution will allow you to crop photos a little more aggressively. The older 645D is going to be behind when it comes to sensor innovation.
