To provide a panoramic photographing system capable of providing a panoramic image in different optical axis directions.
The system comprises a panorama lens barrel 110 and an imaging lens barrel 120, to which an optical axis is orthogonal. The imaging lens barrel 120 includes an incident pupil surface 121. The panoramic lens barrel 110 has a panorama lens 10, a relay lens 12, and a reflective element 14. The panorama lens 10 has a convex annular incident surface S1 on an object side, a convex annular reflective surface S2 on an imaging side, which reflects light made incident on from the annular incident surface S1, a concave circular reflective surface S3 on the object side, which reflects light from the annular reflective surface S2, and a convex circular emission surface S4 on the imaging side, which emits light from the circular reflective surface S3 toward the imaging side. The light beam from the circular emission surface S4 is transmitted to the incident pupil surface 121 via the relay lens 12, and a panoramic image 123 is formed by the imaging lens barrel 120.
