Title:
ZOOM LENS AND CAMERA DEVICE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2022/222085
Kind Code:
A1
Abstract:
A zoom lens (2) capable of being telescopically accommodated, comprising, in order from the object side to the image side: a first lens group (G1), a second lens group (G2) and a P lens group (G3) along an optical axis (C). The first lens group (G1) has negative refractive power; and the second lens group (G2) has a reflective optical element that causes the optical axis (C) to be bent. During telescopic accommodation, the second lens group (G2) moves along the optical axis (C) to the image side, and at least a portion of the first lens group (G1) is telescopically accommodated in a space generated due to the movement of the second lens group (G2), and therefore, a wide angle can be achieved while achieving the thinness and miniaturization during the telescopic accommodation.
