More often than not, it can be hard to picture the contrast in sensor measurements merely by going through technical specs. The photograph here might provide you a stronger sense of the sensor sizing in the K100D S and S1.

As you have seen, both the cameras feature different megapixels and different sensor measurements. The K100D S because of its bigger sensor is going to make getting shallow depth of field less difficult and the Pentax S1 will provide greater detail utilizing its extra 8 Megapixels. Higher resolution will help you crop shots way more aggressively. The older K100D S will be disadvantaged when it comes to sensor technology.
