Abstract

The invention provides a zoom lens which has good resolution and is easy to assemble. The zoom lens comprises a first lens group and a second lens group. The first lens group and the second lens group are adapted to move relative to each other so as to zoom the zoom lens between the wide-angle end and the telephoto end; when the zoom lens is switched from the wide-angle end to the relay position, the first lens group is adapted to move toward the image side; and when the zoom lens is switched from the relay position to the telephoto end, the first lens group is adapted to move toward the object side.

Description

Technical field [0001] The present invention relates to a lens, in particular, to a zoom lens. Background technique [0002] The current mobile phone lens is required to use multiple lenses to match each other when performing a telephoto modified to achieve the desired magnification, however, the varying photo will drop the photo resolution, and with the number of lenses, assembly The difficulty will also increase. Inventive content [0003] The present invention provides a zoom lens having a good resolution and is easy to assemble. [0004] The zoom lens of the present invention includes a first lens group and a second lens group. The first lens group includes a first lens, a second lens, a third lens, and a fourth lens that are sequentially arranged from the object side. The second lens group is disposed between the first lens group and the image side and includes a fifth lens, sixth lens, seventh lens, and eighth lens that are sequentially arranged from the object side onto t...
