摘要： The zoom lens consists of, in order from an object side, a positive first lens group, a negative second lens group, a negative third lens group, and a positive fourth lens group. During zooming from a wide-angle end to a telephoto end, the second lens group moves to an image side, and the third lens group moves to the image side after moving to the object side. The fourth lens group consists of, in order from the object side, a positive fourth A lens group, a negative fourth B lens group moving during image blur correction, a positive fourth C lens group, a fourth D lens group moving during focusing, and a fourth E lens group having a refractive power with a sign different from that of a refractive power of the fourth D lens group.

摘要： A folded telephoto lens system may include multiple lenses with refractive power and a light path folding element. Light entering the camera through lens(es) on a first path is refracted to the folding element, which changes direction of the light on to a second path with lens(es) that refract the light to form an image plane at a photosensor. At least one of the object side and image side surfaces of at least one of the lens elements may be aspheric. Total track length (TTL) of the lens system may be 14.0 mm or less. The lens system may be configured so that the telephoto ration (TTL/f) is less than or equal to 1.0. Materials, radii of curvature, shapes, sizes, spacing, and aspheric coefficients of the optical elements may be selected to achieve quality optical performance and high image resolution in a small form factor camera.
