Typically, it's hard to envision the difference between sensor sizes purely by looking at a spec sheet. The pic here will give you a stronger sense of the sensor dimensions in the E-420 and K-5 IIs.

As you can see, the 2 cameras feature different megapixel count and different sensor sizes. The E-420 with its tinier sensor will make shooting shallow DOF harder and the Pentax K-5 IIs will give extra detail because of its extra 6 Megapixels. Greater resolution will let you crop images way more aggressively. The more aged E-420 is going to be disadvantaged with regard to sensor tech.
