After running the K10D through our normal battery of tests and seeing how it performs in real-world situations we can now say with certainty: Pentax has truly arrived in the DSLR category, and the K10D is a serious player in the advanced amateur DSLR game.
Overall image quality is Excellent throughout the ISO range. Color accuracy is Excellent. Noise is exceptionally well controlled all the way through, and Resolution is excellent at all ISOs. In fact, there is less than a 5 percent drop off in resolution from ISO 100 (1925) to ISO 1600 (1845), and noise only climbs from Very Low (1.15) to Low (1.95) from lowest to highest ISO.
The K10D not only proves that Pentax belongs in the big leagues, it's an all-star player.
