1. An optical system, comprising:
a first light folding element;
a second light folding element; and
a lens system comprising one or more lens elements located between the first light folding element and the second light folding element;
wherein the first light folding element redirects light from an object field from a first axis to the lens system on a second axis;
wherein the one or more lens elements in the lens system refract the light to the second light folding element;
wherein the second light folding element redirects the light from the second axis onto a third axis to form an image of the object field at an image plane;
wherein the lens system is movable on two or more axes independently of the first and second light folding elements, and
wherein F-number of the lens system is less than or equal to 2.4, a 35 mm equivalent focal length of the lens system is in a range 80-200 mm, and Z-height of the lens system <6.5 mm.
