As you can tell, each of these cameras posses the exact same sensor measurements albeit different resolution. You can expect the Pentax K-01 to provide you with extra detail with its extra 6MP. Higher resolution will also make it easier to crop photographs somewhat more aggressively. The fresher K-01 should have an advantage when it comes to sensor innovation.
