Plainly, both of the cameras posses different megapixel count and different sensor dimensions. The E-400 featuring a smaller sensor is going to make getting shallow DOF more difficult and the Olympus E-400 will show greater detail due to its extra 4 Megapixels. Greater resolution will also make it easier to crop photos somewhat more aggressively.
