    摘要： A correction optical member can be locked and unlocked without wasting electric power or requiring cumbersome operations. A locking control member (16) for operating a locking member (20) in synchronism with movement of a lens barrel for holding an optical system including a correction optical member (17a) between a collapsed state and a photographing preparation state is arranged. The locking member is operated in synchronism with a projecting operation of the lens barrel from the collapsed state to the photographing preparation state and a retracting operation of the lens barrel from the photographing preparation state to the collapsed state, so that the correction optical member is set in a swingable state or is locked at a predetermined position.

    摘要： The present invention relates to a deflecting device for deflecting a flux of passing light rays by causing an optical member to move in a plane perpendicular to or approximately perpendicular to the optical axis of an optical system, such as a photographic optical system, in parallel with the plane and making the optical axis of the movable optical member eccentric with respect to the optical axis of the optical system, or to an optical apparatus, such as an image-shake correcting device, for correcting an image shake by the deflection of a pencil of passing light rays. In such a device, there is provided an adjusting mechanism, such as an eccentric shaft or mechanism for supporting the optical members at a plurality of supporting points, for adjusting an inclination of the optical axis of the movable optical member with respect to the optical axis of the optical system to make both the optical axes parallel to each other. According to the above-described arrangement, it is possible to maintain the optical performance of the device or the apparatus at a high level without increasing the precision of constituent elements of mechanism for supporting the movable optical member.

    摘要： An optical apparatus and a camera are provided, which have line-of-sight detecting means, and are capable of selecting a proper AF point selected even if the actually detected line of sight deviates significantly from the observer's intention and capable of reducing the time required for selecting the AF point. A plurality of focus detecting areas are provided on an observing screen, from which focus information on a subject is detected. A line-of-sight detecting device picks up an image of an eyeball of the user to detect the location of a gazing point of the user, A grouping circuit groups the focus detecting areas into a plurality of groups with priorities based on the detected location of the gazing point. A selecting circuit selects one of the groups according to the priorities and selects at least one focus detecting area from the selected group.
