As you can tell, each of the cameras come with different megapixel count and different sensor sizes. The E-330 using its larger sensor is going to make achieving shallower DOF easier and the Pentax I-10 will result in extra detail using its extra 5MP. Greater resolution will enable you to crop photos a good deal more aggressively. The more aged E-330 will be disadvantaged with regard to sensor technology.
