Description
この発明は、アダプターに関するものである。 The present invention relates to adapter.
本発明は、上記の事情に鑑み成されたものであって、交換レンズの絞り駆動部材が開放絞り位置に位置しているときの可動部材の位置を正確に検出することができるアダプターを提供することを目的とする。 The present invention was made in view of the above circumstances, it provides the adapter to the position of the movable member can be accurately detected when the diaphragm driving member of the interchangeable lens is positioned in the open aperture position The purpose is to do.
本発明の第１の態様のアダプターは、カメラボディを着脱可能な第１マウント部と、絞りを有する交換レンズを着脱可能な第２マウント部と、前記絞りの開口径を変化させるための可動部材と、前記絞りが開放となるときの前記可動部材の位置に基づいて、前記可動部材を制御する制御部と、を備える。 The adapter according to the first aspect of the present invention includes a first mount part to which a camera body can be attached and detached, a second mount part to which an interchangeable lens having a diaphragm can be attached and detached, and a movable member for changing the aperture diameter of the diaphragm. And a control unit that controls the movable member based on the position of the movable member when the aperture is opened .
本発明によれば、交換レンズを交換した際にも、絞り駆動部材の開放絞り状態での位置情報（開放絞り位置）に基づき、交換レンズの真の開放絞り状態を基準とした絞り制御を可能とした、アダプターを提供することができる。 According to the present invention, even when the interchangeable lens is replaced, it is possible to perform aperture control based on the true open aperture state of the interchangeable lens based on the position information (open aperture position) of the aperture drive member in the fully open aperture state. and was, it is possible to provide the adapter.
