Plainly, both of these cameras enjoy different megapixels and different sensor dimensions. The E-P1 because of its tinier sensor is going to make shooting shallower depth of field harder and the Olympus E-P1 will give you greater detail having its extra 2 Megapixels. Greater resolution can also allow you to crop photos far more aggressively. The younger E-P1 provides an advantage when it comes to sensor innovation.
