Generally, it can be tough to imagine the difference between sensor sizes just by reading through technical specs. The pic below may give you a greater sense of the sensor sizing in the TG-830 iHS and K100D.

As you can tell, both of these cameras feature different resolutions and different sensor sizes. The TG-830 iHS with its tinier sensor is going to make achieving shallower DOF harder and the Olympus TG-830 iHS will give extra detail having an extra 10 Megapixels. Greater resolution will also let you crop pics way more aggressively. The more modern TG-830 iHS should have a benefit when it comes to sensor technology.
