摘要： Disclosed is a zoom lens optical system including: 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. At least one of the second lens group, the third lens group, and the fourth lens group is moved to vary magnification. The second lens group is moved to perform focus adjustment when a distance to an object is changed between a long distance to a short distance, and the distance from a first lens of the first lens group to an imaging surface is fixed even when the lens moves during a change in magnification and the focus adjustment.According to the invention, it is possible to maintain high resolution with a simple structure during auto focusing from a short distance to a long distance, and it is also possible to achieve an optical system with a small size.
