Normally, it is hard to envision the difference in sensor measurements purely by researching specifications. The visual below should offer you a greater sense of the sensor sizes in the NX20 and A7 III.

Plainly, the 2 cameras offer different resolutions and different sensor measurements. The NX20 featuring a smaller sensor will make achieving shallower depth of field tougher and the Sony A7 III will render more detail as a result of its extra 4MP. Higher resolution can also let you crop pictures a little more aggressively. The older NX20 will be disadvantaged when it comes to sensor technology.
