Usually, it can be tough to envision the gap between sensor sizing only by reviewing a spec sheet. The visual here will provide you a stronger sense of the sensor measurements in the Fujifilm X-S1 and K-S1.

Clearly, both cameras posses different resolutions and different sensor sizing. The Fujifilm X-S1 with its tinier sensor will make getting shallower depth of field tougher and the Pentax K-S1 will offer extra detail with its extra 8 Megapixels. Greater resolution can also allow you to crop pics somewhat more aggressively. The older Fujifilm X-S1 is going to be disadvantaged in sensor technology.
