To sum up, each of these cameras come with the identical sensor size albeit not the same MP. You can count on the Pentax K-S2 to offer you more detail due to its extra 4 Megapixels. Higher resolution will also help you crop pictures a good deal more aggressively. The older D5100 is going to be behind in sensor technology.
