Typically, it is difficult to visualize the difference in sensor measurements only by seeing a spec sheet. The photograph here should offer you a more clear sense of the sensor dimensions in the E-M1 and DP1s.

As you can see, both of these cameras offer different resolutions and different sensor measurements. The E-M1 because of its smaller sensor is going to make getting shallow depth of field more challenging and the Olympus E-M1 will show greater detail utilizing its extra 11 Megapixels. Greater resolution can also enable you to crop images a little more aggressively. The more recent E-M1 provides an edge with regard to sensor innovation.
