Clearly, the two cameras posses different megapixels and different sensor sizing. The K-1 featuring a larger sensor is going to make achieving bokeh easier and the Pentax K-1 will offer greater detail as a result of its extra 16 Megapixels. Greater resolution can also enable you to crop photos somewhat more aggressively. The younger K-1 should have a benefit when it comes to sensor tech.
