技术领域Technical field

本申请涉及一种光学成像镜头，更具体地，本申请涉及一种包括七片透镜的长焦镜头。The present application relates to an optical imaging lens, and more particularly, to a telephoto lens including seven lenses.

背景技术Background technique

由于例如智能手机等便携式电子设备具有良好的便携性，使得这些便携式电子设备的应用越来越普及。人们希望使用便携式电子设备就能在野外实现对较远距离景物的拍摄需求。这就要求镜头在具有长焦特性的同时，还需要具备小型化特性和高成像品质。然而，现有的长焦镜头通常会通过增加透镜片数以实现高成像质量，因而尺寸较大，无法同时满足长焦、小型化与高成像质量的要求。Due to the good portability of portable electronic devices such as smart phones, the application of these portable electronic devices has become more and more popular. It is hoped that the use of portable electronic devices will enable the shooting of distant scenes in the wild. This requires the lens to have telephoto characteristics while also requiring miniaturization characteristics and high image quality. However, the existing telephoto lens usually achieves high image quality by increasing the number of lenses, and thus has a large size, and cannot meet the requirements of telephoto, miniaturization, and high image quality at the same time.

It should be understood that the detailed description is only illustrative of the exemplary embodiments of the present application, and is not intended to limit the scope of the application. Throughout the specification, the same drawing reference numerals refer to the same elements. The expression "and/or" includes any and all combinations of one or more of the associated listed items.

应注意，在本说明书中，第一、第二、第三等的表述仅用于将一个特征与另一个特征区分开来，而不表示对特征的任何限制。因此，在不背离本申请的教导的情况下，下文中讨论的第一透镜也可被称作第二透镜或第三透镜。It should be noted that in the present specification, the expressions of the first, second, third, etc. are used to distinguish one feature from another, and do not represent any limitation of the feature.
