As you can see, each of these cameras posses different megapixels and different sensor measurements. The K-3 due to its bigger sensor will make shooting bokeh simpler and the Pentax K-3 will produce greater detail as a result of its extra 14MP. Higher resolution can also allow you to crop photographs somewhat more aggressively. The younger K-3 is going to have an edge when it comes to sensor tech.
