Sometimes, its hard to envision the gap between sensor sizes only by looking at technical specs. The image below will give you a stronger sense of the sensor measurements in the FS25 and K-S1.

As you can tell, each of these cameras enjoy different megapixel count and different sensor sizes. The FS25 featuring a tinier sensor will make achieving shallow DOF more challenging and the Pentax K-S1 will resolve greater detail having its extra 8MP. Greater resolution will make it easier to crop images far more aggressively. The more aged FS25 is going to be behind with regard to sensor tech.
