Oftentimes, it can be tough to picture the contrast between sensor sizing merely by reading through specifications. The visual below may offer you a more clear sense of the sensor sizes in the TG-3 and K110D.

To sum up, both of those cameras enjoy different resolutions and different sensor sizing. The TG-3 using its tinier sensor is going to make achieving shallower DOF harder and the Olympus TG-3 will give you more detail using its extra 10MP. Greater resolution will also make it easier to crop pics far more aggressively. The newer TG-3 provides an advantage when it comes to sensor innovation.
