Zusammenfassung:	An image taking optical system including a main optical system for forming an object image; and an image splitting unit for dividing an image without re-forming the image formed by the main optical system. The image splitting unit includes sequentially from the object side a performance correcting optical system and an image splitting unit, and satisfies the following conditional equation:where phih represents the optical power of the performance correcting optical system, Ys represents the maximum image height by the image splitting unit, and betah represents the transverse magnification of the performance correcting optical system.
