Clearly, both the cameras feature different megapixel count and different sensor sizes. The FE-4000 with its smaller sensor is going to make achieving bokeh harder and the Pentax K-3 II will produce greater detail having an extra 12 Megapixels. Greater resolution will let you crop photos way more aggressively. The more aged FE-4000 will be disadvantaged when it comes to sensor technology.
