ABSTRACT:
The present invention offers a solution to the undesirable creep or movement of the movable part of a camera zoom lens after it has been adjusted as to focus and/or focal length but before the picture has been taken, resulting usually because the heavy lens part moves axially when the camera is tilted during activities intervening between setting of the lens and snapping the shutter. The device comprises a base attachable to a fixed part of the camera and a tongue attached to the base and adapted to engage the movable part of the lens. The tongue and the movable lens part are provided with interengageable material such as Velcro for effecting a temporary connection between the tongue and the adjusted lens part. The tongue is hinged to the base for swinging toward and away from the movable lens part so as to achieve connection and disconnection of the Velcro-equipped parts. In one form of the invention, the base is attachable to the camera body. In another form, the base has a clamp part adapted to frictionally grasp the fixed lens part.
