Quite often, its hard to picture the contrast in sensor measurements only by looking through a spec sheet. The graphic here will help offer you a far better sense of the sensor sizing in the GH3 and Efina.

Clearly, each of these cameras enjoy different megapixel count and different sensor measurements. The GH3 having a bigger sensor is going to make getting shallower depth of field less difficult and the Panasonic GH3 will render extra detail because of its extra 2 Megapixels. Higher resolution will also enable you to crop shots far more aggressively. The older GH3 will be behind with regard to sensor technology.
