Normally, it can be difficult to picture the gap between sensor measurements just by reviewing a spec sheet. The photograph here may offer you a far better sense of the sensor sizes in the SZ-15 and K-S1.

Clearly, both of those cameras offer different resolutions and different sensor measurements. The SZ-15 having a tinier sensor is going to make achieving shallow depth of field trickier and the Pentax K-S1 will deliver more detail using its extra 4 Megapixels. Greater resolution can also allow you to crop images a little more aggressively. The older SZ-15 is going to be disadvantaged when it comes to sensor technology.
