Abstract
An apparatus which includes an optical system and a driving member. The optical system is shiftable from an origin position coinciding with an optical axis of the apparatus, to reduce image vibration affecting the apparatus. The driving member is movable from a first position to a second position. When the driving member is in the first position, the optical system is unlocked and is therefore shiftable to reduce image vibration. When the driving member moves from the first position to the second position and the optical system is not at the origin position, the driving member guides the optical system to, and then locks the optical system at, the origin position.
