To sum up, both the cameras posses different megapixels and different sensor measurements. The TG-3 with its smaller sensor will make achieving shallow depth of field more difficult and the Olympus TG-3 will produce more detail using its extra 1 Megapixels. Higher resolution will also enable you to crop photographs somewhat more aggressively. The more recent TG-3 will have a benefit when it comes to sensor tech.
