Abstract

Disclosed is an improved interlocked zooming apparatus used in a two-barrel type stereo scopic camera. The improved interlocked zooming apparatus includes an adjusting apparatus for adjusting the range of movement of one of the zoom lenses and an automatic image magnification adjusting apparatus for matching the rates of the change in size of images formed by two cameras. Since the sizes of the images in each of the wide-angle end and the telephoto end are first made uniform by the adjusting apparatus before sensing an image, the sizes of the images formed by both the cameras are uniform over the entire zoom region.
