Often, it's tough to envision the gap between sensor sizing only by reading a spec sheet. The visual underneath should offer you a far better sense of the sensor sizing in the E-M5 and K-5 II.

As you can see, both cameras feature the identical MP albeit not the same sensor sizing. The E-M5 has the tinier sensor which should make obtaining shallower depth of field more difficult. The older E-M5 is going to be disadvantaged when it comes to sensor tech.
