Panasonic G9 vs Sony A9 Sensor Comparison

In many cases, it is very difficult to picture the difference between sensor dimensions purely by reading technical specs. The picture here will give you a more clear sense of the sensor dimensions in the G9 and A9.

As you can tell, both cameras come with different megapixels and different sensor dimensions. The G9 with its tinier sensor is going to make achieving shallow depth of field harder and the Sony A9 will offer greater detail with its extra 4 Megapixels. Higher resolution will also let you crop shots a good deal more aggressively. The fresher G9 provides an edge in sensor technology.
