In many cases, it's hard to picture the contrast in sensor dimensions only by viewing technical specs. The picture here will help give you a greater sense of the sensor sizes in the TG-820 iHS and GR.

As you can tell, both cameras provide different megapixels and different sensor dimensions. The TG-820 iHS using its smaller sensor is going to make shooting shallow DOF harder and the Ricoh GR will render greater detail using its extra 4MP. Higher resolution will make it easier to crop pictures more aggressively. The more aged TG-820 iHS will be disadvantaged when it comes to sensor technology.
