Typically, it is very tough to visualize the difference in sensor sizes merely by going through a spec sheet. The pic below should provide you a far better sense of the sensor sizing in the LZ20 and 645D.

Clearly, the 2 cameras feature different resolutions and different sensor sizes. The LZ20 using its smaller sensor is going to make shooting shallow depth of field tougher and the Pentax 645D will show greater detail because of its extra 24MP. Greater resolution will also enable you to crop photos way more aggressively. The younger LZ20 provides an advantage when it comes to sensor technology.
