1. A dual-aperture digital camera for imaging an object or scene, comprising:

  • a) a Wide camera comprising a Wide lens and a Wide image sensor, the Wide camera having a respective field of view FOVW and being operative to provide a Wide image of the object or scene;

    b) a Tele camera comprising a Tele lens and a Tele image sensor, the Tele camera having a respective field of view FOVT narrower than FOVW and being operative to provide a Tele image of the object or scene, wherein the Tele lens has a respective effective focal length EFLT and total track length TTLT fulfilling the condition EFLT/TTLT>

    1;

    c) a first autofocus (AF) mechanism coupled mechanically to, and used to perform an AF action on the Wide lens;

    d) a second AF mechanism coupled mechanically to, and used to perform an AF action on the Tele lens; and

    e) a camera controller operatively coupled to the first and second AF mechanisms and to the Wide and Tele image sensors and configured to control the AF mechanisms and to process the Wide and Tele images to create a fused image, wherein areas in the Tele image that are not focused are not combined with the Wide image to create the fused image and wherein the camera controller is further operative to output the fused image with a point of view (POV) of the Wide camera by mapping Tele image pixels to matching pixels within the Wide image.
