Clearly, both of these cameras offer different megapixel count and different sensor sizing. The K-1 II because of its larger sensor is going to make getting shallower depth of field simpler and the Pentax K-1 II will provide extra detail due to its extra 12 Megapixels. Greater resolution can also enable you to crop photos a little more aggressively. The newer K-1 II provides an advantage when it comes to sensor innovation.
