To sum up, each of the cameras offer the same exact sensor sizing albeit different resolution. You should count on the Olympus E-M1 to deliver greater detail having its extra 4 Megapixels. Higher resolution will let you crop shots a little more aggressively. The more recent E-M1 provides an advantage in sensor tech.
