Abstract
A camera having a hand tremor correction mechanism with improved positioning of the hand tremor correction mechanism. The camera includes a photographic lens which moves along the optical axis of the photographic optical system. A vibration detection unit detects camera vibration, such as from hand tremor, and produces a corresponding output signal. A vibration correction mechanism, coupled to the external periphery of the photographic lens and electrically connected to the vibration detection unit via a flexible printed circuit board, receives the output signal of the vibration detection unit and compensates for the vibration detected by the vibration detection unit. The camera can also have a vibration correction mechanism which is coupled to the external periphery of the photographic lens and which shifts the photographic lens to compensate for the effects of vibration, the vibration correction mechanism having a thickness or width in the optical axis direction which is less than or equal to the thickness or width of the photographic lens in the optical axis direction.
