Pentax Q7 vs Sony A7S Sensor Comparison

          

          

            
In many cases, it can be difficult to see the gap in sensor sizes only by viewing technical specs. The pic here might provide you a better sense of the sensor sizing in the Q7 and A7S.
As you can tell, the 2 cameras have the same MP albeit not the same sensor sizes. The Q7 has got the smaller sensor which is going to make achieving shallow DOF tougher. The more aged Q7 will be disadvantaged in sensor technology.
