Normally, it is very tough to imagine the difference in sensor measurements just by seeing specs. The photograph here may provide you a greater sense of the sensor dimensions in the K-5 IIs and RX1R II.

All in all, both the cameras feature different megapixels and different sensor measurements. The K-5 IIs with its smaller sensor is going to make achieving bokeh harder and the Sony RX1R II will provide more detail having an extra 26 Megapixels. Higher resolution will allow you to crop photographs way more aggressively. The older K-5 IIs will be disadvantaged when it comes to sensor technology.
