An optical system for shooting a three-dimensional image and a three-dimensional image shooting apparatus using the optical system produces an image with a smaller amount of light leaked from the side to be cut off over an entire image frame when parallax images are obtained by employing a shutter in which the extinction ratio varies depending on an incident angle. The optical system includes a pair of front optical components each having negative optical power, an optical member for superimposing optical axes of the pair of front optical components with each other, a rear optical component disposed to have an optical axis aligned with the superimposed optical axes, and a shutter capable of independently controlling amounts of transmitted light incident upon the pair of front optical components from an object. The shutter is disposed between the pair of front optical components and the rear optical component. The optical system forms parallax images in a time series by alternately changing the amount of transmitted light incident upon the pair of front optical components from the object with the shutter.
