Pentax K-3 vs Pentax K10D Sensor Comparison

Normally, it is very hard to visualize the difference between sensor dimensions purely by reading a spec sheet. The pic below may give you a greater sense of the sensor sizes in the K-3 and K10D.

As you can see, each of the cameras enjoy the same exact sensor sizing albeit different MP. You should expect the Pentax K-3 to offer you extra detail because of its extra 14 Megapixels. Higher resolution can also enable you to crop shots far more aggressively. The more recent K-3 should have an advantage in sensor tech.
