Plainly, both cameras offer different megapixels and different sensor dimensions. The E-400 due to its tinier sensor will make shooting shallower DOF more difficult and the Sony A390 will resolve more detail due to its extra 4 Megapixels. Higher resolution can also enable you to crop shots a little more aggressively. The more aged E-400 is going to be disadvantaged in sensor tech.
