All in all, the two cameras come with the identical sensor size but different resolution. You should anticipate the Pentax K-S1 to give you extra detail having its extra 4 Megapixels. Greater resolution will enable you to crop photos a good deal more aggressively. The older K-5 is going to be behind when it comes to sensor technology.
