Title:
ZOOM LENS, CAMERA MODULE, AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2023/274041
Kind Code:
A1
Abstract:
A zoom lens, a camera module, and a mobile terminal, The zoom lens comprises a first lens group (G1) and a second lens group (G2) arranged from an object side to an image side: the first lens group (G1) is fixed, and the second lens group (G2) can slide along the optical axis; the first lens group (G1) has positive focal power, and the second lens group (G2) has negative focal power; the ratio of the focal length EFLG1 of the first lens group (G1) to the focal length EFLG2 of the second lens group (G2) satisfies: 0.4<|EFLG1/EFLG2|<1.22; the ratio of the focal length EFLG2 of the second lens group (G2) to the focal length EFL of an optical lens satisfies: 0.4<|EFLG2/EFL|<1. By combing the two lens groups, the lens can be applied to photographing scenes at a long distance and a micro distance; compared with existing lenses compatible with a long distance and a micro distance, a miniaturization requirement is met, and higher resolution and better aberration control are achieved.
