From p.63 in the manual. "When (multi-auto white balance) is set,even if various light sources are present at the shooting location, the camera automatically adjusts the white balance according to the light source of each area." Basically it will use different WB settings in different areas of the same image. For example an interior lit by tungsten lighting where a window has an outdoor view, in theory both these areas should have their appropriate white balances set. The K-3 had this feature as well.

When mounting a Sigma 12-24mm EX DG, camera will sometimes (but not always) ask to have focal length input, even though this lens doesn't require this for use with a K-3 or K-5. If I enter the default 100mm and then try to check it in the menu, the focal length item in the menu (camera 4) is greyed out, as it should be for a lens with the appropriate electrical contacts. Examining the EXIF data of an image shot at 12mm, the focal length appears as the correct 12mm. I realize that it's probably a Sigma firmware issue, but I'm surprised that it doesn't happen every time the camera is turned on with this lens mounted.
