Typically, it can be hard to see the difference between sensor measurements only by reviewing a spec sheet. The visual underneath will help offer you a better sense of the sensor sizing in the K-3 and K-7.

Clearly, each of these cameras have the same sensor dimensions albeit not the same resolution. You can expect the Pentax K-3 to offer extra detail having its extra 9MP. Higher resolution will make it easier to crop photographs a bit more aggressively. The newer K-3 will have an advantage when it comes to sensor technology.
