More often than not, it is hard to envision the contrast between sensor sizing just by checking technical specs. The photograph underneath may offer you a clearer sense of the sensor sizing in the GM1 and RS1500.

As you have seen, both of the cameras enjoy different resolutions and different sensor sizing. The GM1 using its bigger sensor will make achieving shallow DOF simpler and the Panasonic GM1 will give you more detail having an extra 2MP. Higher resolution will also make it easier to crop photographs far more aggressively. The newer GM1 is going to have an edge when it comes to sensor technology.
