More often than not, its tough to picture the difference in sensor dimensions just by seeing a spec sheet. The picture below will help provide you a far better sense of the sensor measurements in the E-M5 and NEX-7.

Clearly, the two cameras feature different megapixel count and different sensor dimensions. The E-M5 due to its smaller sensor is going to make getting shallow DOF harder and the Sony NEX-7 will show more detail as a result of its extra 8 Megapixels. Greater resolution will enable you to crop photos way more aggressively.
