Olympus TG-610 vs Pentax 645D Sensor Comparison
Oftentimes, it's hard to visualize the gap in sensor dimensions only by viewing specifications. The pic here will help provide you a stronger sense of the sensor sizes in the TG-610 and 645D.
Plainly, both the cameras offer different megapixel count and different sensor dimensions. The TG-610 because of its smaller sensor is going to make shooting shallower DOF trickier and the Pentax 645D will render extra detail due to its extra 26 Megapixels. Higher resolution will enable you to crop photographs a little more aggressively. The more recent TG-610 should have an advantage with regard to sensor technology.
