The present embodiments relates to a lens driving device including: a housing; a bobbin disposed in the housing; a coil disposed on the bobbin; a first magnet which is disposed on the housing and faces the coil; a second magnet disposed on the bobbin; and a sensor which is disposed on the housing and faces the second sensor, wherein the sensor includes an upper surface, a lower surface disposed opposite the upper surface, an inner surface facing the second magnet, an outer surface disposed opposite the inner surface, and both lateral surfaces connecting the inner surface with the outer surface, the upper surface and the lower surface of the sensor are fixed to the housing, and one of the side surfaces of the sensor is opened.

A lens unit with a central axis is provided. The lens unit includes a fixed portion, a movable portion, and a first driving assembly. The fixed portion includes an outer frame and a bottom combined with the outer frame. The outer frame and the bottom are arranged along the central axis. The movable portion is movably connected to the fixed portion, and carries a lens with an optical axis. The central axis is not parallel to the optical axis. The first driving assembly is connected to the movable portion, and drives the movable portion to move relative to the fixed portion. The first driving assembly also includes a biasing element made of a shape memory alloy.

An optical element driving mechanism is provided, including a fixed portion, a movable portion, a driving assembly, and a stopping assembly. The movable portion is movably connected to the fixed portion, wherein the movable portion is used for connecting to an optical element having a main axis. The driving assembly is disposed on the fixed portion or the movable portion, and the driving assembly is used for driving the movable portion to move relative to the fixed portion. The stopping assembly is connected to the movable portion and the fixed portion.

A lens for a still or film camera includes a first and second lens-element arrangement, and a wavefront manipulator. The first and second lens-element arrangement are arranged spaced mutually apart along an optical axis of the lens such that an interstice is present therebetween. The wavefront manipulator is situated in the interstice and includes at least two optical components which are arranged so as to be displaceable counter to one another, perpendicular to the optical axis, and which each include a free-form surface. The wavefront manipulator has a zero position, in which the optical components thereof do not cause any image aberrations in the imaging properties of the lens, and effective positions, in which the optical components are displaced counter to one another, out of the zero position perpendicular to the optical axis, and in which the optical components cause a spherical aberration in the imaging properties of the lens.
