Description

technical field

[0001] The present application relates to the field of optical elements, 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 groups 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 the 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 therein will also interfere with the image quality to a certain extent.

[0003] In view of the gradual miniaturization of portable electronic products such as smartphones, the optical imaging lens group applied to them should meet the charact...
