摘要：
A zoom lens optical system includes: a first lens group that is provided close to an object, has a negative refractive power in total, and includes an optical part having a surface that reflects light; a second lens group that has a negative refractive power in total; an iris; a third lens group that has a positive refractive power in total; and a fourth lens group that has a positive refractive power in total.
