1. A camera, comprising:
an optical path folding element (OPFE) for a folding a first optical path OP1 to second optical path OP2;
a lens including a plurality of lens elements divided into four lens groups arranged along a lens optical axis and marked, in order from an object side of the lens to an image side of the lens, G1, G2, G3 and G4; and
an image sensor,
wherein the camera is a folded Tele camera,
wherein the lens elements of a lens group do not move with respect to each other,
wherein G1 and G3 do not move with respect to each other,
wherein G2 and G4 do not move with respect to each other,
wherein the Tele camera is configured to change a zoom factor (ZF) continuously between a minimal zoom factor marked ZFMIN corresponding to a minimal effective focal length marked EFLMIN and a maximal zoom factor marked ZFMAX corresponding to a maximal effective focal length marked EFLMAX by moving G1 and G3 together relative to the image sensor and by moving G2 and G4 together relative to the image sensor,
wherein ZFMAX/ZFMIN≥1.5,
wherein the camera is included in a camera module having a module height HM,
wherein the lens has a lens aperture height HA,
wherein both HM and HA are measured along an axis parallel to OP1, and
wherein HM<HA+3 mm.
