Samsung NX20 vs Sony A7S II Sensor Comparison

Sometimes, it is very difficult to envision the contrast in sensor measurements purely by checking out a spec sheet. The visual underneath should give you a clearer sense of the sensor measurements in the NX20 and A7S II.

As you can see, the two cameras provide different megapixels and different sensor measurements. The NX20 having a smaller sensor will make getting shallower DOF harder and the Samsung NX20 will produce extra detail using its extra 8MP. Greater resolution will help you crop photos more aggressively. The older NX20 will be behind with regard to sensor technology.
