Typically, it is very difficult to picture the gap between sensor sizes purely by reading a spec sheet. The picture underneath should offer you a greater sense of the sensor dimensions in the EX-FH25 and A7S III.

As you can see, both of those cameras offer different resolutions and different sensor sizes. The EX-FH25 featuring a tinier sensor is going to make shooting shallow DOF harder and the Sony A7S III will offer you extra detail as a result of its extra 2 Megapixels. Greater resolution can also let you crop images a little more aggressively. The more aged EX-FH25 is going to be disadvantaged with regard to sensor tech.
