As you can see, the 2 cameras posses different megapixels and different sensor dimensions. The TG-810 with its smaller sensor is going to make getting shallower DOF trickier and the Pentax K-3 II will render extra detail because of its extra 10MP. Higher resolution will let you crop pictures somewhat more aggressively. The more aged TG-810 will be behind in sensor innovation.
