Abstract
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.
