Panasonic GH6 vs Sony A7R III Sensor Comparison

In many cases, it is very tough to imagine the contrast between sensor dimensions merely by reading a spec sheet. The picture here should give you a better sense of the sensor sizing in the GH6 and A7R III.

Clearly, both the cameras have got different megapixel count and different sensor dimensions. The GH6 due to its tinier sensor is going to make shooting bokeh more difficult and the Sony A7R III will offer extra detail having its extra 17 Megapixels. Higher resolution will make it easier to crop pictures much more aggressively. The younger GH6 should have an advantage in sensor tech.
