As you can tell, each of the cameras offer the same exact sensor sizing albeit different megapixels. You should expect the Pentax K-30 to produce extra detail because of its extra 1MP. Higher resolution can also make it easier to crop shots a little more aggressively. The more recent K-30 should have an advantage in sensor technology.
