As you can tell, both of the cameras have different megapixel count and different sensor dimensions. The E-400 having a larger sensor is going to make achieving shallow DOF easier and the Pentax Efina will give extra detail having an extra 4 Megapixels. Greater resolution can also make it easier to crop photos a bit more aggressively. The more aged E-400 is going to be behind in sensor innovation.
