摘要： An optical equipment with a lens position control device for a zoom lens of inner focus type, enabling a faster focusing operation and also enabling focusing to an object of a very short distance, regardless of the initial state of the zoom lens. The equipment is provided with a first detector for detecting the zoom state, a second detector for detecting the focus state, and a controller varying the control of the zooming lens group and the focusing lens group according to the zooming state. When the focusing lens is to be moved to a position for focusing to a shorter distance, the controller drives the focusing lens group and the zooming lens group during the same time, only if the zooming lens group is at the wide angle side with respect to a predetermined zoom state, thus reducing the focusing time without a significant change in the image angle.

摘要： 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.
