Often, it is tough to visualize the difference between sensor sizing only by looking at a spec sheet. The graphic below might provide you a clearer sense of the sensor sizes in the FS12 and A7R III.

Clearly, both the cameras come with different resolutions and different sensor sizing. The FS12 because of its tinier sensor is going to make getting shallower DOF more challenging and the Sony A7R III will give you extra detail having its extra 30 Megapixels. Higher resolution will allow you to crop pictures a good deal more aggressively. The older FS12 is going to be disadvantaged with regard to sensor innovation.
