Oftentimes, it is hard to visualise the gap in sensor measurements merely by looking through a spec sheet. The visual underneath may provide you a greater sense of the sensor dimensions in the A7R III and QX100.

Clearly, both cameras enjoy different megapixels and different sensor measurements. The A7R III featuring a bigger sensor will make shooting shallower depth of field less difficult and the Sony A7R III will result in more detail due to its extra 22 Megapixels. Higher resolution will also make it easier to crop photographs far more aggressively. The more modern A7R III is going to have an edge when it comes to sensor innovation.
