To sum up, both of those cameras offer different megapixel count and different sensor sizes. The FZ100 with its smaller sensor is going to make achieving bokeh harder and the Pentax K-S1 will provide more detail having an extra 6 Megapixels. Greater resolution will help you crop photos a little more aggressively. The more aged FZ100 will be disadvantaged when it comes to sensor innovation.
