Abstract
An optical system includes a pair of front optical components, an optical member for superposing respective optical axes of the pair of front optical components on each other, a rear optical component disposed such that the superimposed optical axes coincide with an optical axis of the rear optical component, the rear optical component including a lens unit arranged to move during zooming, and a lens unit arranged to move during focusing and disposed on an object side of the lens unit arranged to move during zooming, and a pair of shutters capable of independently controlling amounts of transmission of light fluxes respectively entering the pair of front optical components from an object. The optical system forms parallactical images in a time-series manner by causing the pair of shutters to alternately change the amounts of transmission of light fluxes respectively entering the pair of front optical components from the object.
