光学系に入射した被写体からの光の光量調節を出し入れすることにより行うＮＤフィルターと、An ND filter that performs by adjusting the amount of light from a subject incident on the optical system;
前記ＮＤフィルターの状態を検知するＮＤ位置状態検出手段を有し、ND position state detection means for detecting the state of the ND filter,
前記ＮＤ位置状態検出手段は、前記ＮＤフィルターが挿入状態であるか、前記ＮＤフィルターが外れた状態か、または前記ＮＤフィルターが移行期間中であるかを検知する検出手段を有することを特徴とする光学装置。The ND position state detection means has detection means for detecting whether the ND filter is in an inserted state, a state where the ND filter is removed, or whether the ND filter is in a transition period. Optical device. 濃度の異なるＮＤフィルターを備え、光量調節に用いられているＮＤフィルターを検出することを特徴とする請求項１の光学装置。The optical apparatus according to claim 1, further comprising an ND filter having a different density and detecting an ND filter used for light amount adjustment. 更に、絞りを有し、前記ＮＤフィルターが移行期間の場合、前記絞りの絞り制御の状態を通常の制御と異なる制御とすることを特徴とする請求項１または２の光学装置。3. The optical device according to claim 1, further comprising an aperture, wherein when the ND filter is in a transition period, the aperture control state of the aperture is controlled differently from normal control. 前記通常の制御と異なる制御は、絞り動作を固定することであることを特徴とする請求項３の光学装置。4. The optical apparatus according to claim 3, wherein the control different from the normal control is to fix a diaphragm operation. 前記通常の制御と異なる制御は、絞り動作をスローシャッタ動作とすることを特徴とする請求項３の光学装置。4. The optical apparatus according to claim 3, wherein the control different from the normal control is a slow shutter operation. 請求項１〜５の光学装置と、撮影装置とから構成され、前記光学装置から、前記ＮＤフィルターの状態を前記撮影装置に通信することを特徴とする撮影システム。 Imaging system and an optical apparatus according to claim 1 to 5, is composed of a photographing device, from the optical device, and wherein the communicating state of the ND filter to the imaging device.
