ABSTRACT:
A taking lens capable of being used for photographing by light in each of at least two wavelength regions including a first wavelength region and a second wavelength region is provided and include: the flange back adjusting lens; a storing unit that stores a correcting amount of the flange back adjusting lens in photographing by light in the second wavelength region; and the lens driving unit. When the taking lens is used in photographing by light in the first wavelength region, the lens driving unit moves the flange back adjusting lens to a set position adjusted at the flange back; and when the taking lens is used in photographing by light in the second wavelength region, the lens driving unit moves the flange back adjusting lens based on the correcting amount so that an image location in photographing by light in the second wavelength region coincides with an image location in photographing by light in the first wavelength region.
