Usually, it is difficult to envision the gap in sensor sizing only by viewing technical specs. The graphic here may give you a clearer sense of the sensor sizes in the GM1 and NEX-7.

As you have seen, both of these cameras have different resolutions and different sensor sizing. The GM1 due to its smaller sensor will make shooting shallow depth of field harder and the Sony NEX-7 will provide you with more detail having its extra 8MP. Greater resolution will also enable you to crop images a bit more aggressively. The fresher GM1 is going to have an advantage when it comes to sensor technology.
