    摘要: This application provides an optical lens, a camera module, and an electronic device. The optical lens includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens that are sequentially arranged from an object side to an image side. The first lens, the third lens, and the fifth lens all have positive focal power, the second lens and the fourth lens both have negative focal power, and the sixth lens has positive focal power or negative focal power. Object side surfaces and image side surfaces of the first lens to the sixth lens include at least one anamorphic aspherical surface. When the optical lens is applied to the camera module and the electronic device, the camera module and the electronic device can implement ultra-wide-angle photographing, and can also resolve a distortion problem in ultra-wide-angle imaging to a large degree.

    摘要: A lens support mechanism (10) comprises a fourth lens group unit (24), a sixth lens group unit (26), a rectilinear cylinder 11, a cam cylinder (12), and a guide shaft (29a). The rectilinear cylinder 11 is provided on the outer peripheral side of the fourth lens group unit 24 and the sixth lens group unit 26, and has a rectilinear groove 11e into which a cam follower 24b and a main cam follower 26ba are inserted to restrict the rotation of the fourth lens group unit 24. A cam groove 12e and a cam groove 12h with which the cam follower 24b and the main cam follower 26ba are engaged are formed in the cam cylinder 12, and when the cam cylinder 12 rotates with respect to the rectilinear cylinder 11, this moves the fourth lens group unit 24 and the sixth lens group unit 26 in the optical axis OP direction. The guide shaft 29a is fixed at a first end to the fourth lens group unit 24 and inserted into the insertion opening 26c to guide the sixth lens group unit 26 in the optical axis OP direction.

    摘要: An optical imaging lens includes a first lens element to a sixth lens element from an object side to an image side along an optical axis. An optical axis region of the object-side surface of the first lens element is concave, a periphery region of the object-side surface of the second lens element is convex, a periphery region of the image-side surface of the fourth lens element is concave, an optical axis region of the object-side surface of the fifth lens element is convex and a periphery region of the image-side surface of the sixth lens element is convex. Lens elements included by the optical imaging lens are only six lens elements described above. ImgH is an image height of the optical imaging lens and AAG is a sum of five air gaps from the first lens element to the sixth lens element along the optical axis to satisfy ImgH/AAG≥3.200.
