1. A camera module, comprising:
a lens with N=6 lens elements Li divided into a first lens group (G1) having at least two lens elements, and a second lens group (G2), and having an effective focal length EFL, an aperture diameter DA, a f-number f/#, a total track length TTL and a back focal length BFL, wherein each lens element has a respective focal length fi and wherein a first lens element L1 faces an object side and a last lens element LN faces an image side;
an object side optical path folding element O-OPFE for folding a first optical path (OP1) to a second optical path (OP2);
an image side optical path folding element I-OPFE for folding OP2 to a third optical path (OP3), wherein OP1 and OP2 are perpendicular to each other and wherein OP1 and OP3 are parallel with each other; and
an image sensor having a sensor diagonal (SD),
wherein the camera module is a folded digital camera module, wherein G1 is located at an object side of the O-OPFE and G2 is located at an image side of the O-OPFE, wherein the EFL is in the range of 8 mm<EFL<50 mm, wherein the camera module is divided into a first region having a minimum camera module region height MHM and including G1 and the O-OPFE, and into a second region having a minimum shoulder region height MHS<MHM and including the I-OPFE and the image sensor, wherein all heights are measured along OP1, wherein an aperture height of the lens is HL and wherein HL/MHS>0.9, and wherein a cut plane of the cut lens group G2 is parallel to OP2 and parallel to an axis perpendicular to both OP1 and OP2.
