As you can see, each of these cameras enjoy different resolutions and different sensor dimensions. The TG-810 because of its smaller sensor will make shooting shallower depth of field harder and the Pentax K-5 will provide extra detail as a result of its extra 2 Megapixels. Higher resolution will make it easier to crop shots far more aggressively. The newer TG-810 is going to have an advantage when it comes to sensor tech.
