Normally, it's difficult to envision the gap between sensor sizing simply by going over technical specs. The visual here will give you a much better sense of the sensor sizes in the TG-830 iHS and K-S1.

As you have seen, each of the cameras have different megapixels and different sensor sizing. The TG-830 iHS with its tinier sensor will make achieving shallow depth of field more difficult and the Pentax K-S1 will offer you extra detail with its extra 4MP. Greater resolution can also make it easier to crop pics a bit more aggressively. The older TG-830 iHS is going to be behind in sensor tech.
