Plainly, the two cameras enjoy different megapixels and different sensor dimensions. The TG-870 using its smaller sensor is going to make achieving shallow depth of field more difficult and the Olympus TG-870 will render greater detail because of its extra 1MP. Higher resolution will help you crop pictures far more aggressively. The newer TG-870 provides a benefit when it comes to sensor technology.
