Abstract: A zoom lens includes a first lens group, a second lens group, a third lens group, and a fourth lens group that are sequentially arranged from an object side to an image side along an optical axis. The first lens group and the third lens group are fastened, and the second lens group and the fourth lens group move along the optical axis. A first lens from the object side in the first lens group is a biconvex lens, and at least two lenses from the object side in the first lens group are glass lenses. A maximum clear aperture diameter of the zoom lens has the following relationship of 4 mm≤φ≤12 mm, where p is the maximum clear aperture diameter of the zoom lens.

Abstract: Embodiments of this application disclose a zoom lens, a camera module, and a mobile terminal. The zoom lens includes a first lens group, a second lens group, a third lens group, and a fourth lens group that are arranged along an object side to an image side. The first lens group is a fixed lens group with positive focal power, the second lens group is a zoom lens group with negative focal power, the third lens group is a compensative lens group with positive focal power, and the fourth lens group is a fixed lens group with positive focal power. In a zooming process of the zoom lens from a short-focal end to a long-focal end, the second lens group moves towards the image side along an optical axis, and the third lens group moves towards the object side along the optical axis.

Abstract: An optical lens for use in a camera module comprises a first lens and a second lens that are sequentially arranged from an object side to an image side. An object side surface of the first lens and an object side surface of the second lens are convex surfaces. The first lens has an Abbe number vd1, with 60≤vd1≤90. The first lens has a refractive index nd1, the second lens has a refractive index nd2, with 1.65≤nd2≤2, and 0.2≤nd2−nd1≤0.5. The second lens has an Abbe number vd2, with 40

Abstract: A zoom lens, a camera module, and a mobile terminal. The zoom lens includes a first lens group, a second lens group, and a third lens group arranged along an axis extending from an object side to an image side, where the first lens group is a fixed lens group with positive focal power nearest an object side, where the second lens group is a zoom lens group with negative focal power, where the third lens group is a compensative lens group with positive focal power nearest an image side to an image side, and where the second lens group is configured to move, in a zooming process of the zoom lens from a short-focal end to a long-focal end, toward the image side along an optical axis, and the where third lens group is configured to move toward the object side along the optical axis.
