Panasonic G100 vs Sony a1 Sensor Comparison

		

		

			
Usually, it can be difficult to envision the difference between sensor dimensions only by reviewing specifications. The pic below should provide you a stronger sense of the sensor sizes in the G100 and a1.
Plainly, the 2 cameras provide different resolutions and different sensor dimensions. The G100 having a tinier sensor will make shooting shallower depth of field more difficult and the Sony a1 will offer greater detail using its extra 30MP. Higher resolution will enable you to crop shots more aggressively. The more aged G100 is going to be behind when it comes to sensor tech.
