Panasonic G9 vs Sony A7S III Sensor Comparison
Usually, it is very hard to see the gap in sensor sizes only by researching specifications. The picture here might offer you a much better sense of the sensor sizes in the G9 and A7S III.
To sum up, both of the cameras offer different megapixels and different sensor sizes. The G9 because of its smaller sensor will make getting shallow DOF more challenging and the Panasonic G9 will result in extra detail as a result of its extra 8MP. Greater resolution can also help you crop photos a little more aggressively. The more aged G9 will be disadvantaged in sensor innovation.
