ABSTRACT:
A lens control apparatus for controlling a lens apparatus having an extender is provided. When an operation of storing a shot is performed in a shot box connected to the lens apparatus having an extender, a memory stores data including a position of a zoom lens group at that time, a position of a focus lens group at that time, and a magnification of the extender at that time. When an operation of reproducing the shot is performed, a CPU transmits a control signal for moving the zoom lens group and the focus lens group to positions represented by the shot. In addition, the CPU transmits to the lens apparatus a control signal for setting the magnification of the extender at a value of the magnification thereof represented by the stored shot.
