Plainly, each of the cameras posses the exact same sensor measurements but not the same resolution. You should anticipate the Pentax K-3 to deliver greater detail having its extra 21MP. Greater resolution will also allow you to crop images somewhat more aggressively. The more aged D30 is going to be disadvantaged when it comes to sensor technology.
