The Pentax K10D is based around an APS-C sized CCD imager with an effective resolution of 10.2 megapixels. It uses a 22-bit Analog-to-digital converter (output is 8-bit JPEG or 12-bit RAW), and a new processing engine dubbed "PRIME" (Pentax Real IMage Engine). This is coupled with a Pentax KAF lens mount that's compatible with an impressive array of K-, KA-, KAF- and KAF2 lenses, as well as screw-mount / 645-system / 67-system lenses with an adapter. Pentax also notes that the camera body is designed to be compatible with new "supersonic motor-driven" AF lenses which are currently in development.
