ABSTRACT:
A variable magnification optical system includes lens units that focus a ray of light from an object side on an image sensor, in which the lens unit located at a first position from the object side toward the image side includes an optical path changing element for changing an optical path. The variable magnification optical system performs magnification variation by changing gaps between the lens units, and satisfies predetermined conditional formulae.
