The camera position is fixed when the camera is focused on the object at the close object distance set by the macro-photographing setting device. When the zoom operation means is actuated, at least one of the whole-unit driving device and the relative drive device are actuated to keep the focused state for the close object distance.

摘要： A zoom lens is disclosed which comprises a front lens group for collecting light as a first group, a magnification varying lens group for varying the magnification of an image as a second group, a compensator lens group for correcting defocussing and performing a focus adjustment as a third group, and a master lens group for allowing an image of an object to be formed on an image pickup plane. In the zoom lens, the compensator lens group is brought into contact with the compensator lens group positioned at the end of a tele photographing side and, with this state, these two lens groups are moved together to a wide photographing side. Thanks to this, in the tele side photography, a close-up picture taking of several cm can be realized.

摘要： A lens system comprises a converging first lens group, a diverging second lens group and a converging third lens group arranged in this order as viewed from the object side. The lens can focus continuously from infinity down to a very short object distance by moving only the diverging second lens forward and rearward along the optical axis. The paraxial rays exiting from the second lens group and incident on the third lens group are kept always substantially in parallel with the optical axis throughout all the moving range for focusing of the second lens group.

摘要： A zoom lens capable of macro-photography includes first and second movable lenses coupled to first and second cam rings, respectively. The first and second cam rings are operatively associated so that they rotate as a unit about the optical axis of the lens to axially move the first and second lenses for zooming, but are capable of relative axial movement with respect to one another at any point within the zooming range of the lens to move one lens relative to the other lens for macro-photography.

摘要： A mechanical mounting system for a zoom objective having provision for close-up operation includes an actuator serving to perform both focusing and zooming operations as it is turned and axially moved respectively. When the actuator is axially moved to the wide angle position and when it is turned to the lower limit of the focusing range, a drive connection between the actuator and a camming cylinder for the zoom and close-up control is established even in the transverse direction. Upon transverse movement of the actuator beyond the focusing range, the camming cylinder is turned to axially move the variator forwardly while the compensator remains stationary in the wide angle position thereby effecting a close-up operation.
