Sometimes, it is very tough to picture the difference between sensor dimensions merely by going over technical specs. The pic below will offer you a stronger sense of the sensor measurements in the K20D and WG-2 GPS.

As you can tell, both of those cameras posses different resolutions and different sensor dimensions. The K20D using its bigger sensor is going to make shooting shallower depth of field easier and the Pentax WG-2 GPS will deliver extra detail because of its extra 1 Megapixels. Higher resolution will let you crop shots somewhat more aggressively. The more aged K20D is going to be behind when it comes to sensor tech.
