Pentax Q vs Samsung NX20 Sensor Comparison

Oftentimes, it's tough to visualize the difference between sensor sizing simply by going over technical specs. The visual below will offer you a better sense of the sensor measurements in the Q and NX20.

As you have seen, both the cameras come with different resolutions and different sensor sizing. The Q having a tinier sensor is going to make shooting shallower depth of field more difficult and the Samsung NX20 will offer more detail because of its extra 8MP. Higher resolution will enable you to crop pictures a good deal more aggressively. The older Q is going to be disadvantaged when it comes to sensor innovation.
