Typically, it is very tough to picture the difference between sensor measurements just by going over specifications. The graphic here will help give you a better sense of the sensor sizes in the S5 and 645D.

Plainly, each of these cameras offer different megapixels and different sensor measurements. The S5 with its tinier sensor is going to make shooting shallower depth of field harder and the Pentax 645D will deliver extra detail because of its extra 16 Megapixels. Greater resolution will also let you crop images a little more aggressively. The more recent S5 provides an advantage with regard to sensor innovation.
