Olympus 5010 vs Pentax K20D Sensor Comparison

Clearly, both of these cameras posses different megapixel count and different sensor sizing. The 5010 having a smaller sensor will make shooting shallow depth of field trickier and the Pentax K20D will result in more detail with its extra 1MP. Greater resolution will make it easier to crop images somewhat more aggressively. The more modern 5010 is going to have a benefit with regard to sensor tech.
