Generally, it is very tough to visualise the gap in sensor measurements simply by researching technical specs. The visual below will help offer you a better sense of the sensor sizing in the WG-10 and A7R.

As you have seen, each of these cameras have different megapixel count and different sensor measurements. The WG-10 having a smaller sensor will make achieving shallower DOF tougher and the Sony A7R will result in greater detail with its extra 22 Megapixels. Greater resolution can also make it easier to crop images a bit more aggressively. The older WG-10 will be behind when it comes to sensor innovation.
