Clearly, each of these cameras offer different megapixels and different sensor dimensions. The E-PL9 having a smaller sensor is going to make achieving shallower depth of field tougher and the Olympus E-PL9 will render extra detail with its extra 1 Megapixels. Greater resolution can also enable you to crop pics a little more aggressively. The newer E-PL9 provides a benefit with regard to sensor tech.
