Abstract: Folded digital cameras comprising a lens system with a lens and an image sensor, the lens having N≥6 lens elements Li, an effective focal length (EFL) and a total track length (TTL), wherein each lens element has a respective focal length fi and wherein a first lens element L1 faces an object side, and an optical path folding element (OPFE) for providing a folded optical path between an object and the lens. In some embodiments, the lens system has a focusing range that covers object-lens distances from infinity to a minimal object distance (MIOD), wherein MIOD/EFL is smaller than 20 or even 7. In some embodiments, the ratio of a maximal chief ray angle to a field of view of the folded camera Max CRA/FOV is smaller than 0.25 or even 0.15 when the camera is focused at infinity.

Abstract: Dual-aperture digital cameras with auto-focus (AF) and related methods for obtaining a focused and, optionally optically stabilized color image of an object or scene. A dual-aperture camera includes a first sub-camera having a first optics bloc and a color image sensor for providing a color image, a second sub-camera having a second optics bloc and a clear image sensor for providing a luminance image, the first and second sub-cameras having substantially the same field of view, an AF mechanism coupled mechanically at least to the first optics bloc, and a camera controller coupled to the AF mechanism and to the two image sensors and configured to control the AF mechanism, to calculate a scaling difference and a sharpness difference between the color and luminance images, the scaling and sharpness differences being due to the AF mechanism, and to process the color and luminance images into a fused color image using the calculated differences.

Abstract: Actuators for actuating a lens in a folded camera, folded cameras including such actuators and dual-cameras including such folded cameras. The actuators actuate a lens having a lens optical axis for auto-focus (AF) and optical image stabilization (OIS) and comprise a stationary sub-assembly that includes an OIS coil having an OIS coil plane and an AF coil having an AF coil plane, and a lens actuating sub-assembly movable relative to the stationary sub-assembly with a lens holder holding the lens, wherein the OIS coil plane is perpendicular to the AF coil plane and wherein the lens optical axis lies between the OIS coil plane and the AF coil plane. Some actuators have a design using VCM actuation and a reduced height due to top and/or bottom openings in actuator envelopes.
