Panasonic G9 vs Sony A77 II Sensor Comparison

		

		

			
Often, its hard to imagine the gap between sensor sizing simply by going over specifications. The visual here will give you a far better sense of the sensor sizing in the G9 and A77 II.
Plainly, both of the cameras offer different megapixels and different sensor sizing. The G9 featuring a tinier sensor is going to make getting shallow DOF more difficult and the Sony A77 II will offer you extra detail as a result of its extra 4 Megapixels. Greater resolution will help you crop pics a little more aggressively. The more recent G9 provides an edge when it comes to sensor technology.
