Often, it is very hard to visualize the contrast in sensor dimensions merely by going through specs. The image below will help give you a better sense of the sensor dimensions in the TG-870 and K-01.

As you can plainly see, the 2 cameras come with the identical MP albeit different sensor dimensions. The TG-870 provides the smaller sensor which is going to make getting shallow DOF more difficult. The newer TG-870 provides an edge in sensor technology.
