Oftentimes, it is hard to visualize the difference between sensor measurements purely by reading through technical specs. The photograph underneath may provide you a clearer sense of the sensor dimensions in the SH-3 and K-S2.

As you can tell, the two cameras offer different megapixel count and different sensor measurements. The SH-3 featuring a tinier sensor is going to make shooting shallower depth of field tougher and the Pentax K-S2 will give you more detail as a result of its extra 4MP. Higher resolution can also allow you to crop photographs a little more aggressively. The more modern SH-3 should have a benefit when it comes to sensor tech.
