Often, its tough to visualize the gap between sensor sizing simply by reading through a spec sheet. The visual here will help give you a stronger sense of the sensor sizes in the TG-310 and K-30.

As you can see, both the cameras posses different megapixel count and different sensor sizing. The TG-310 due to its tinier sensor is going to make achieving shallower DOF tougher and the Pentax K-30 will resolve greater detail as a result of its extra 2MP. Higher resolution can also allow you to crop photographs somewhat more aggressively. The older TG-310 is going to be disadvantaged in sensor innovation.
