The K-30 features the state-of-the-art SAFOX IXi+ AF sensor module, which assures responsive, high-precision autofocus operation by incorporating a diffraction lens to minimize chromatic aberration in accordance to the characteristics of each individual lens. It also factors the light source at the time of shooting into its calculations. Nine of its 11 sensor points have cross-type sensors to capture all kinds of subjects in sharp focus, while its spotbeam projector assists the AF system at poorly lit locations. The K-30’s AF algorithm has also been upgraded in all areas. A new select-area expansion function allows the sensor module to continue to track a moving subject, even when it moves out of a pre-assigned auto-tracking area, by assessing distance data collected by neighboring focus sensors. The accuracy and speed of detecting moving subjects during autofocus shooting, and autofocusing performance when using a telephoto lens, have been greatly improved as well.
