Abstract: A lens system provides a zoom function (variable magnification) in a low profile camera (lens system height less than or equal to 6 mm), which may be in a cellular phone. The lens system includes at least three movable lens groups that are movable along a common optical axis. Each of the three movable lens groups is coupled to a corresponding actuator. Responsive to a request to change focal length or magnification, a controller sends a corresponding signal to each of the actuators that move the corresponding lens group by a corresponding distance in a corresponding direction. The various movable lens groups may be moved by different distances and in different directions of movement. An f-number of the lens system is less than f/3.0. Focusing of an image cast onto an image sensor is accomplished by adjusting the position along the optical axis of one of the movable lens groups.

Abstract: Various embodiments disclosed herein include zoom lens assemblies, as well as cameras and devices that incorporate these zoom lens assemblies. The zoom lens assemblies described herein include three lens groups, the first of which includes a light-folding element such as a prism. The second and third lens groups are moveable relative to the first lens group and relative to each other to change the focal length of the camera.
