Panasonic G100 vs Sony A7R III Sensor Comparison
Sometimes, it can be tough to see the difference in sensor sizing purely by looking through technical specs. The graphic below may give you a better sense of the sensor sizes in the G100 and A7R III.
As you have seen, both the cameras have different megapixels and different sensor sizing. The G100 because of its smaller sensor will make shooting shallower DOF harder and the Sony A7R III will result in greater detail as a result of its extra 22MP. Higher resolution can also allow you to crop photographs a bit more aggressively. The fresher G100 will have a benefit with regard to sensor technology.
