The E-M1X featuring a tinier sensor is going to make getting shallower DOF harder and the Olympus E-M1X will offer greater detail as a result of its extra 4 Megapixels. Greater resolution will make it easier to crop pics much more aggressively. The younger E-M1X should have an edge when it comes to sensor technology.
