Oftentimes, it is very tough to picture the gap in sensor sizing merely by going through specifications. The photograph here should offer you a greater sense of the sensor measurements in the G7 and A7R III.

Plainly, both the cameras enjoy different resolutions and different sensor sizing. The G7 using its smaller sensor is going to make getting shallow DOF trickier and the Sony A7R III will provide extra detail with its extra 26MP. Higher resolution will also help you crop shots far more aggressively. The older G7 will be disadvantaged in sensor innovation.
