    Abstract: Folded Tele cameras comprising an optical path folding element (OPFE) for folding a first optical path OP1 to a second optical path OP2, a lens including N=8 lens elements, the lens being divided into three lens groups numbered, in order from an object side of the lens, G1, G2 and G3, and an image sensor, wherein G1 and G3 are included in a single G13 carrier, wherein G2 is included in a G2 carrier, wherein both the G13 carrier and the G2 carrier include rails for defining the position of G2 relative to G13, wherein the Tele camera is configured to change a zoom factor continuously between a minimum zoom factor ZFMIN and a maximum zoom factor ZFMAX by moving the G2 carrier relative to the G13 carrier and by moving the G13 carrier relative to the image sensor, and wherein an effective focal length (EFL) is 7.5 mm

    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.

    Abstract: Position sensing units, comprising a magnetic assembly (MA) having a width W measured along a first direction and a height H measured along a second direction and including at least three magnets having respective magnetic polarizations that define along the first direction at least a left MA domain, a middle MA domain and a right MA domain, wherein the magnetic polarizations of each MA domain are different, and a magnetic flux measuring device (MFMD) for measuring a magnetic flux B, wherein the MA moves relative to the MFMD along the first direction within a stroke L that fulfils 1 mm≤L≤100 mm, stroke L beginning at a first point x0 and ending at a final point xmax, and wherein a minimum value Dmin of an orthogonal distance D, measured along the second direction between a particular MA domain and the MFMD, fulfills L/Dmin>10.
