However, in the conventional stereo photographing apparatus, the left and right lenses 1 and 2 are used as described above.
Are arranged in parallel, and when the subject 3 to be photographed is at a short distance, as shown in FIG. 6, the subject image 6 is shifted toward the outer end. That is, since the right lens 1 and the left lens 2 are arranged at a predetermined interval, the subject image 6 is shifted to the right in the right lens 1 and to the left in the left lens 2, and the left and right images overlap 100.
Becomes smaller. Therefore, the subject region that can be stereoscopically viewed becomes narrow, and a good stereoscopic image cannot be obtained. In addition, since the light beam from the subject 3 is obliquely incident on the right lens 1 and the left lens 2, a geometrical shape such that the circular subject 3 becomes elliptical as shown in the subject image 6 in FIG. There is a problem that a large distortion occurs.

The one in which the deflection lens systems 9 and 10 are arranged is used. It should be noted that a mirror, a wedge prism, or the like can be used instead of the deflection lens systems 9 and 10. According to this, the eccentric lens system 9, 1
If the respective cylindrical lenses La of 0 are shaken outward according to the distance, the principal rays of the left and right lenses 7 and 8 are directed to the center of the subject 3, thereby reducing the above-mentioned subject area and geometrically. The distortion is eliminated. However, in this case, as described above, a mechanism for driving the two left and right lenses 7 and 8 for focusing and a mechanism for driving the cylindrical lens La in accordance with the distance in the deflection lens systems 9 and 10. Two mechanisms are required, resulting in a problem that the configuration becomes complicated and the device becomes large.
