1. A compact camera module, comprising an image sensor configured to couple to a flexible printed circuit to power the camera module and transmit images captured at the image sensor; an optical train aligned with the image sensor that includes multiple lenses including at least one movable lens coupled to an actuator to form an optical system that is configured to automatically adjust a position of the at least one movable lens along the optical path to focus an object disposed within an auto-focus range of the camera module onto the image sensor; an EMI housing configured to contain the optical train and to shield camera module components from electromagnetic interference (EMI), the EMI housing having defined therein a focus-adjustment aperture that is large enough to permit an object end of the optical train to at least partially protrude therethrough at one end of the auto-focus range; and a light leak baffle that has a baffle aperture defined therein that partially overlaps the focus-adjustment aperture along said optical path, the light leak baffle comprising EMI shield material that partially overlaps the focus adjustment aperture in the direction of the optical path but outside said one end of the auto-focus range.
