Claim 5:
6. The variable magnification optical system according to claim 1, wherein in a state where the variable magnification optical system focuses on an object at infinity and the variable magnification optical system is in a zooming state in which a focal length of the variable magnification optical system is shortest,
assuming that
fw is a focal length of the variable magnification optical system,
ωw is a half angle of view of the variable magnification optical system, and
Dexpw is a distance on an optical axis from a lens surface closest to the image side in the variable magnification optical system to an exit pupil position of the variable magnification optical system,

Conditional Expression (3) is satisfied, which is represented by

0<|{fw×tan(ωw)}/Dexpw|<0.2  (3).
