Panasonic G9 vs Sony A7S II Sensor Comparison

Normally, it is very difficult to visualise the contrast between sensor sizes only by going over technical specs. The picture underneath might provide you a more clear sense of the sensor dimensions in the G9 and A7S II.

As you have seen, each of the cameras have got different megapixel count and different sensor sizes. The G9 due to its tinier sensor will make shooting bokeh tougher and the Panasonic G9 will offer you greater detail as a result of its extra 8MP. Greater resolution can also enable you to crop photos much more aggressively. The newer G9 is going to have an edge when it comes to sensor tech.
