As you can plainly see, the two cameras posses different megapixel count and different sensor sizes. The VG-120 using its tinier sensor will make getting shallower DOF more difficult and the Pentax K-3 will give greater detail using its extra 10MP. Higher resolution will also make it easier to crop shots somewhat more aggressively. The more aged VG-120 is going to be disadvantaged in sensor tech.
