In many cases, it is very difficult to imagine the difference between sensor sizing merely by reviewing technical specs. The graphic here will offer you a clearer sense of the sensor sizes in the GH5 II and a1.

As you can tell, each of these cameras have different resolutions and different sensor sizing. The GH5 II due to its tinier sensor is going to make achieving shallower depth of field trickier and the Sony a1 will offer extra detail as a result of its extra 30MP. Greater resolution can also make it easier to crop images a bit more aggressively. The more modern GH5 II provides an advantage with regard to sensor innovation.
