Generally, it can be difficult to envision the difference in sensor measurements only by checking out specifications. The photograph here should offer you a clearer sense of the sensor sizing in the WG-3 GPS and a1.

Plainly, each of the cameras have different megapixels and different sensor measurements. The WG-3 GPS because of its smaller sensor will make achieving shallower DOF harder and the Sony a1 will provide more detail as a result of its extra 34MP. Higher resolution will help you crop shots a bit more aggressively. The older WG-3 GPS will be disadvantaged with regard to sensor innovation.
