A method for operating an autofocus system for focusing an image on an electronic imager includes providing an adjustable lens system defining an optical path for scene light and having at least one movable lens to focus an image of the scene onto the electronic imager; and causing a first portion of the scene light to be obscured so that the electronic imager captures a first autofocus image and causing a second different portion of the scene light to be obscured so that the electronic imager captures a second autofocus image wherein portions of the first and second autofocus images are offset. The method further includes moving the movable lens to a position so that an image to be captured will be in focus.
