Abstract
An image-shake preventing device or an optical axis deflecting device includes a lock part arranged to lock a movable optical member when the state of a barrier member comes to block incident light and when the position of a photo-taking optical system is either outside of a normal shooting area or in the neighborhood of a wide-angle end position. This arrangement obviates the necessity of providing the device with any operation part, a driving part, etc., solely for the purpose of locking the movable optical member and thus permits reduction in size and cost of the device. When the movable optical member must be locked, the arrangement also enables the device to adequate lock the movable optical member.
