Often, it can be tough to see the contrast in sensor dimensions just by seeing a spec sheet. The pic here might give you a better sense of the sensor measurements in the GF7 and A3000.

As you can see, the 2 cameras enjoy different megapixel count and different sensor dimensions. The GF7 using its smaller sensor will make getting shallower DOF harder and the Sony A3000 will produce greater detail because of its extra 4MP. Higher resolution will make it easier to crop shots far more aggressively. The younger GF7 is going to have an advantage when it comes to sensor innovation.
