レンズ鏡筒。[Scope of Claim for Utility Model Registration] 1. As the front group lens moves in the direction of the photographing optical axis, the rear group lens moves in and out of the photographing optical axis, resulting in photography using only the front group lens and combined optics of both the front and rear lens groups. 1. A lens barrel for a variable focus camera capable of switching between shooting and shooting using a variable focus camera, characterized in that a rear group lens is held by a cylindrical member whose optical axis center is decentered. 2. A lens mirror for a variable focus camera according to claim 1 of the utility model registration claim, characterized in that it is provided with an eccentric rotating member that allows adjustment of the position at which the rear group lens moves and stops on the photographing optical axis. Tube.
