Normally, it's tough to imagine the gap between sensor sizing purely by going over specs. The visual below will help offer you a clearer sense of the sensor sizing in the EX-Z800 and A7S III.

All in all, both of those cameras enjoy different megapixel count and different sensor sizing. The EX-Z800 with its tinier sensor is going to make getting shallower depth of field trickier and the Casio EX-Z800 will offer you greater detail because of its extra 2MP. Higher resolution will also allow you to crop photographs far more aggressively. The older EX-Z800 is going to be disadvantaged when it comes to sensor technology.
