Claims (1)
しその後方に副レンズを撮影光軸上に挿入した長焦点距
離撮影とに切換え可能な可変焦点カメラにおいて、焦点
距離切換え時に主レンズを主レンズの光軸方向に移動す
るための鏡筒操作部材を設け、該操作部材に長焦点距離
用視野枠を設けたことを特徴とする可変焦点カメラ。In a variable focus camera that can switch between short focal length photography using the main lens and long focal length photography by moving the main lens forward and inserting a sub lens behind it on the shooting optical axis, the main lens is switched to the main lens when changing the focal length. A variable focus camera characterized in that a lens barrel operation member for moving in the optical axis direction of a lens is provided, and a long focal length field frame is provided on the operation member.
