More often than not, it is difficult to imagine the gap in sensor sizes only by going through specifications. The image here should offer you a greater sense of the sensor dimensions in the E-510 and RS1500.

Plainly, the 2 cameras posses different megapixels and different sensor sizes. The E-510 with its larger sensor is going to make getting shallow DOF less difficult and the Pentax RS1500 will show greater detail having an extra 4MP. Greater resolution will help you crop photos somewhat more aggressively. The more aged E-510 will be disadvantaged with regard to sensor innovation.
