As you can tell, both cameras enjoy different megapixels and different sensor dimensions. The K20D using its larger sensor is going to make shooting shallow DOF less difficult and the Pentax K20D will result in more detail having an extra 3 Megapixels. Greater resolution can also enable you to crop pics far more aggressively. The more aged K20D will be behind in sensor tech.
