To sum up, each of these cameras have different megapixels and different sensor measurements. The TG-810 with its smaller sensor will make shooting shallow depth of field more difficult and the Olympus TG-810 will produce more detail using its extra 2MP. Higher resolution will also make it easier to crop pictures a bit more aggressively. The younger TG-810 is going to have a benefit when it comes to sensor innovation.
