In many cases, its difficult to imagine the gap in sensor measurements simply by viewing a spec sheet. The photograph here might give you a clearer sense of the sensor dimensions in the E-420 and K-500.

Clearly, each of the cameras provide different resolutions and different sensor measurements. The E-420 due to its smaller sensor is going to make shooting shallow DOF trickier and the Pentax K-500 will result in more detail as a result of its extra 6MP. Greater resolution will let you crop photos more aggressively. The older E-420 will be disadvantaged with regard to sensor tech.
