Typically, its difficult to imagine the contrast between sensor measurements simply by reviewing a spec sheet. The graphic underneath should offer you a more clear sense of the sensor sizes in the E-PM2 and A550.

As you can see, both of those cameras posses different megapixels and different sensor measurements. The E-PM2 due to its tinier sensor is going to make achieving shallow depth of field more difficult and the Olympus E-PM2 will offer you more detail as a result of its extra 2 Megapixels. Higher resolution will also make it easier to crop photographs somewhat more aggressively. The newer E-PM2 provides an advantage with regard to sensor innovation.
