A stereoscopic imaging optical system is provided, which forms two optical images having no mutual interference, side-by-side, on a rectangle image sensor, and which is applicable to an interchangeable-lens type digital camera system. The stereoscopic imaging optical system includes a first lens system and a second lens system which are arranged in parallel, and a field diaphragm arranged on the object side relative to these lens systems. The first lens system and the second lens system form optical images of an object on a first imaging area and a second imaging area, respectively. The field diaphragm has an aperture arranged in front of the first lens system and the second lens system. The field diaphragm blocks only a portion of a light beam incident on the first lens system, which portion enters the second imaging area, and blocks only a portion of a light beam incident on the second lens system, which portion enters the first imaging area. |
