Yes, in the AF.S mode, the internal flash in the upright position will fire to provide focus assist for the K10D, Jonathan. Refer to page 131 in the owners manual. This method reduces the need for an additional focus assist lamp, cutting manufacturing costs. Most external flash units provide focus assist as well. However, instead of using flash output to illuminate the subject (as the internal flash does), these units often include a larger, more powerful, focus assist lamp than could easily be squeezed into the typical small camera. Several current Nikon, Canon, and other brand cameras operate roughly the same way, and this trend may spread in the future to other camera models as well.
