As you can tell, both of those cameras posses different megapixel count and different sensor sizes. The E-3 because of its tinier sensor is going to make getting shallow depth of field harder and the Olympus E-3 will resolve more detail due to its extra 5 Megapixels. Higher resolution can also make it easier to crop pictures somewhat more aggressively. The more aged E-3 is going to be disadvantaged with regard to sensor technology.
