Abstract

The present application discloses an optical imaging lens group, which sequentially includes an autofocus assembly, a first lens, a second lens, a third lens, a fourth lens and at least one follow-up lens along the optical axis from the object side to the image side , wherein the radius of curvature of the image side of the autofocus component is variable.

Description

technical field [0001] The present application relates to the field of optical elements, and in particular, to an optical imaging lens set. Background technique [0002] With the rapid development of the lens industry, the imaging quality of optical imaging lens sets used in portable electronic products such as smartphones is getting higher and higher. At the same time, users have more and more requirements for the functions of mobile phone cameras, especially, In terms of zoom characteristics of the lens. At present, most mobile phone cameras on the market use mechanical zoom to realize the zoom function. However, a camera with a mechanical zoom function is bulky and difficult to install in a mobile phone, and the magnets and coils in it will also interfere with the image quality to a certain extent. [0003] In view of the current trend of miniaturization of portable electronic products such as smart phones, the optical imaging lens set applied on them should meet the ch...
