Sometimes, it's tough to envision the contrast in sensor measurements only by looking through specs. The graphic underneath may provide you a stronger sense of the sensor measurements in the E-M1 and DP1 Merrill.

As you can plainly see, both of those cameras have got different resolutions and different sensor measurements. The E-M1 because of its smaller sensor will make getting shallower DOF harder and the Olympus E-M1 will render extra detail due to its extra 1 Megapixels. Greater resolution can also help you crop images much more aggressively. The newer E-M1 is going to have an advantage when it comes to sensor tech.
