Oftentimes, it is very difficult to see the gap in sensor sizes merely by checking out specs. The picture here might give you a far better sense of the sensor dimensions in the TG-810 and K-5 IIs.

As you can plainly see, both of those cameras provide different resolutions and different sensor sizes. The TG-810 using its smaller sensor will make achieving shallow DOF trickier and the Pentax K-5 IIs will show extra detail because of its extra 2 Megapixels. Higher resolution can also enable you to crop pictures more aggressively. The more aged TG-810 will be behind with regard to sensor tech.
