    • A lens hood with lens covers that need not be attached to and detached from a lens unit and are easily openable and closable relative to each other. The lens hood includes a hood body attached to the front of a lens to prevent unnecessary light from being incident upon the lens, a pair of lens covers installed inside the hood body to be pivotable about an axis perpendicular to the optical axis of the lens and movable between a closed position where they will cover the lens and an opened position where they will be outside the field of view of the lens, and a cover operating mechanism that operates in conjunction with the sliding of an operator installed slidably to the hood body to pivot the lens covers in opposite directions, respectively, and to pivot the pair of lens covers between the opened and closed positions.
    • 具有透镜盖的透镜罩,其不需要附接到透镜单元并从透镜单元拆下并且易于相对于彼此打开和关闭。 透镜罩包括安装在透镜前部的罩主体,以防止不必要的光入射到透镜上;一对透镜盖,安装在罩主体内部,以能够围绕垂直于透镜光轴的轴线转动;以及 在它们将覆盖透镜的关闭位置和它们将在透镜的视野之外的打开位置之间移动;以及盖操作机构,其与可滑动地安装到罩主体的操作者的滑动相结合地操作, 分别在相反方向上枢转镜头盖,并且在打开和关闭位置之间枢转一对镜头盖。
