Quite often, it can be hard to envision the gap in sensor sizing just by researching a spec sheet. The visual below might provide you a more clear sense of the sensor sizes in the G1 and A7 III.

Clearly, both of these cameras provide different megapixels and different sensor sizing. The G1 due to its smaller sensor will make getting shallower depth of field tougher and the Sony A7 III will provide you with extra detail as a result of its extra 12 Megapixels. Greater resolution will let you crop photos more aggressively. The older G1 will be disadvantaged when it comes to sensor tech.
