Clearly, both of the cameras have the same sensor dimensions albeit not the same MP. You can count on the Pentax K-3 III to result in more detail having its extra 14 Megapixels. Higher resolution will also help you crop photographs a bit more aggressively. The older D300S will be disadvantaged in sensor technology.
