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.

Zoom lens, camera module, and mobile terminal

The technology of this application relates to a zoom lens, a camera module, and a mobile terminal. The zoom lens includes a plurality of lens groups, for example, a first lens group, a second lens group, a third lens group, a fourth lens group, and a fifth lens group that are arranged from an object side to an image side. The first lens group is a lens group with a positive focal power, the second lens group is a lens group with a negative focal power, and the third lens group is a lens group with a positive focal power. The fourth lens group is a lens group with a positive focal power or a negative focal power, and the fifth lens group is a lens group with a positive focal power or a negative focal power.

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 φ is the maximum clear aperture diameter of the zoom lens.
