摘要： Folded cameras with a total track length (TTL), f numbers smaller than 1.2 and large fields of view, e.g. of at least 60 degrees. Such folded cameras may comprise a lens with N≥7 lens elements, an image sensor and an optical path folding element for providing a folded optical path between an object and the lens, wherein an aperture stop of the lens is located closer to a first surface of the first lens element facing the object than a distance d that fulfills d/TTL=0.2.

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.
