To sum up, both of the cameras come with different resolutions and different sensor measurements. The TG-610 with its smaller sensor will make getting shallower depth of field more difficult and the Olympus TG-610 will render more detail having an extra 8 Megapixels. Higher resolution will also help you crop shots a good deal more aggressively. The newer TG-610 is going to have an advantage with regard to sensor technology.
