    Abstract: The lens arrangement has at least two lenses, wherein a first lens may be used for autofocus and optical image stabilization. The first lens is tilted to compensate for the shaking movement of the hand-held device and to stabilize the image to be captured on the image plane. The tilt action may occur in two degrees of freedom, wherein an actuator causes the first lens to tilt around a pivot. A second lens is a field flattener lens that compensates for the error caused by the difference between the image plane and the focus plane. The field flattener lens causes the focal plane of the first lens to lie in the image plane when the first lens is in a tilted position.
