Plainly, the 2 cameras posses different megapixel count and different sensor dimensions. The E-520 having a smaller sensor will make shooting shallow depth of field trickier and the Pentax K-01 will result in more detail using its extra 6 Megapixels. Higher resolution can also make it easier to crop shots somewhat more aggressively. The more aged E-520 will be disadvantaged in sensor tech.
