Usually, it is tough to envision the gap in sensor sizes purely by looking through a spec sheet. The picture below will help provide you a much better sense of the sensor sizes in the E-400 and RS1500.

As you can see, both of the cameras offer different megapixel count and different sensor sizes. The E-400 due to its bigger sensor will make achieving shallow DOF easier and the Pentax RS1500 will provide you with extra detail having its extra 4MP. Higher resolution will also make it easier to crop pictures a little more aggressively. The more aged E-400 will be disadvantaged with regard to sensor innovation.
