ZOOM LENS AND OPTICAL EQUIPMENT USING THE SAME

Japanese Patent JP2019070690

A

To provide a zoom lens with satisfactory performance capable of handling 4-5 times of zoom magnification in wide angle of view with a simple configuration, and an optical equipment having the same.SOLUTION: The zoom lens includes: a first lens group L1 that has a negative refractive power from the object side to the image side; a second lens group L2 that has a positive refractive index; and a stop SP disposed between the first lens unit L1 and the second lens unit L2. The stop SP is configured to move independently from the other lens groups in a convex locus at the image side when zooming. Defining the travel of the stop SP to the image side as Mimg, the travel of the first lens group L1 as M1, the focal length of the second lens group L2 as f2, and the focal length at the wide angle end as fw, the zoom lens satisfies 0.01
