Normally, it is difficult to see the contrast in sensor measurements purely by viewing specs. The visual underneath might give you a stronger sense of the sensor measurements in the E-520 and RS1500.

All in all, the two cameras have got different megapixel count and different sensor measurements. The E-520 using its bigger sensor will make shooting shallow depth of field easier and the Pentax RS1500 will render extra detail having an extra 4MP. Higher resolution will also enable you to crop pictures much more aggressively. The older E-520 will be disadvantaged with regard to sensor tech.
