The first lens group, the second lens group, the third lens group and the fourth lens group are sequentially arranged in a direction. The aperture is located between the second lens group and the third lens group. When the zoom lens performs a zoom operation, the first lens group and the third lens group are fixed and the second lens group and the fourth lens group are moved, and a moving distance of the fourth lens group on an optical axis of the zoom lens is less than 5 mm."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Zoom lens","description":"A zoom lens includes a first lens group, a second lens group, a third lens group, a fourth lens group and an aperture.
