Compact auto-focus image taking lens system with a micromirror array lens and a lens-surfaced prism

A compact auto-focus image taking lens system with a Micromirror Array Lens and a lens-surfaced prism comprising from an object side to an image side:

• a) a prism having a concave surface on the object side, an internal reflective surface, and a surface on the image side, wherein both sides of the object side and the image sides are aspheric;
• b) an aperture stop;
• c) a first lens element, wherein the first lens element is a negative optical refractive power meniscus shape lens with a convex on the object side, wherein the first lens element is made of plastic with at least one aspheric surface on the object side surface and the image side surface;
• d) a second lens element having a positive optical refractive power;
• e) a Micromirror Array Lens comprising a plurality of micromirrors having reflective surfaces;
• and
• f) an image surface, wherein the image taking lens system makes image on the image surface;
• wherein the Micromirror Array Lens is configured to change focus of the image by controlling the motions of the micromirrors.
