PROBLEM TO BE SOLVED: To provide a visible light/infrared light photographing system which separates subject light made incident on a photographic lens and passing through a focus lens and a zoom lens to subject light in a visible light region and subject light in an infrared light region by a color separation prism or the like, picks up each subject light in terms of image by an imaging device for visible light and an imaging device for infrared light, adjusts the image forming magnification of the subject light in the infrared light region by a correction lens, whereby the image forming magnification of a visible image is made accurately coincident with that of an infrared image, and makes correcting processing for making the image forming magnification coincident unnecessary so that the burden of image processing is lightened and also the improvement of efficiency and accuracy is realized. SOLUTION: The focus lens FL, the zoom lens ZL and the color separation prism P are arranged in the photographic lens 10. The subject light in the visible light region is made incident on the imaging device DA for visible light after it is transmitted through the prism P and passes through a diaphragm IA and a relay lens RLA. The subject light in the infrared light region is made incident on the imaging device DB for infrared light after it is reflected on the prism P and passes through a diaphragm IB and a relay lens RLB including the correction lens ZCL.
