Generally, it is difficult to picture the difference between sensor measurements merely by reading through specs. The photograph here will give you a greater sense of the sensor dimensions in the G7 and a1.

All in all, both of the cameras provide different megapixels and different sensor measurements. The G7 with its tinier sensor is going to make shooting shallower DOF tougher and the Sony a1 will resolve extra detail with its extra 34 Megapixels. Higher resolution can also help you crop shots more aggressively. The older G7 is going to be disadvantaged with regard to sensor innovation.
