Oftentimes, it is hard to see the contrast in sensor measurements only by going through specs. The visual here may provide you a much better sense of the sensor sizing in the K-S1 and KP.

As you can plainly see, both of these cameras have got the exact same sensor measurements albeit not the same resolution. You should count on the Pentax KP to produce greater detail due to its extra 4 Megapixels. Higher resolution can also make it easier to crop photographs much more aggressively. The older K-S1 will be behind with regard to sensor innovation.
