Sometimes, it is difficult to picture the gap between sensor measurements purely by looking at a spec sheet. The visual below might offer you a clearer sense of the sensor measurements in the K-3 and K-3 III.

As you can see, the two cameras posses the exact same sensor measurements but different resolution. You should expect to see the Pentax K-3 III to resolve greater detail having its extra 2 Megapixels. Greater resolution will also allow you to crop images somewhat more aggressively. The older K-3 is going to be behind with regard to sensor technology.
