The K-3 was revealed 7 years after the K10D which is quite a serious gap as far as technology is concerned. The two cameras offer the identical body type (Mid-size SLR).

Before getting through a thorough comparison, below is a quick view of how the K-3 grades against the K10D with regards to portability, imaging, features and an overall mark.

Here is a preview of the gallery images for Pentax K-3 and Pentax K10D. The full galleries are provided at Pentax K-3 Gallery and Pentax K10D Gallery.

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.
