Description

本発明のレンズ装置は、撮像装置に着脱可能であり、前記撮像装置と通信可能なレンズ装置であって、焦点調節に際して移動するフォーカスレンズと、前記フォーカスレンズを駆動する駆動手段と、前記フォーカスレンズの位置を検出する位置検出手段と、前記フォーカスレンズが前記駆動手段により駆動され、かつ、前記フォーカスレンズが無限側の端と至近側の端の間に位置していない場合に、焦点検出動作を禁止することを示す信号を前記撮像装置に送信する制御手段を有することを特徴とする。 Lens system of the present invention is detachably worn on the imaging equipment, and the imaging device capable of communicating lens unit, and focus lens moves during focusing Tencho section driving means for driving the focus lens Position detection means for detecting the position of the focus lens , and when the focus lens is driven by the drive means and the focus lens is not located between the end on the infinite side and the end on the closest side, characterized in that a signal indicating that prohibits the focus detection operation to have a control means to send to the imaging device.
