Samsung NX20 vs Sony A7 IV Sensor Comparison

		

		

			
More often than not, it is difficult to envision the difference between sensor measurements just by reading through technical specs. The photograph below will help provide you a stronger sense of the sensor measurements in the NX20 and A7 IV.
As you can tell, the two cameras have different megapixels and different sensor measurements. The NX20 with its tinier sensor will make achieving shallower depth of field more challenging and the Sony A7 IV will resolve extra detail with its extra 13 Megapixels. Higher resolution will make it easier to crop shots a bit more aggressively. The older NX20 is going to be disadvantaged when it comes to sensor technology.
