Oftentimes, its tough to picture the contrast in sensor sizing merely by viewing specs. The visual below will offer you a better sense of the sensor dimensions in the 645D and Q10.

As you can plainly see, both of those cameras provide different megapixels and different sensor sizing. The 645D having a bigger sensor is going to make getting shallower depth of field easier and the Pentax 645D will render extra detail using its extra 28MP. Higher resolution can also enable you to crop pictures more aggressively. The older 645D will be behind in sensor innovation.
