Clearly, each of these cameras enjoy different megapixels and different sensor sizing. The 1 having a smaller sensor will make shooting shallow DOF tougher and the Olympus 1 will provide more detail having an extra 2 Megapixels. Higher resolution will also let you crop shots far more aggressively. The more modern 1 will have an edge in sensor tech.
