As you can see, both the cameras feature different megapixels and different sensor measurements. The K-5 with its bigger sensor is going to make shooting shallow depth of field simpler and the Pentax K-5 will show greater detail having an extra 6MP. Higher resolution will also let you crop pictures way more aggressively. The fresher K-5 should have an edge with regard to sensor technology.
