Description

一种镜头跟焦器搭载装置
本申请要求于2021年12月08日提交中国专利局、申请号为202111493328.8、发明名称为“一种镜头跟焦器搭载装置”的中国专利申请的优先权。
技术领域
本发明涉及摄影器材技术领域，尤其涉及一种镜头跟焦器搭载装置。
背景技术
在使用相机进行视频拍摄过程中，通常需要搭载跟焦器来辅助对焦、变焦等，传统的跟焦器的搭载方式，是在相机外围套上一个金属笼子，将金属导管固定到金属笼子下方，然后把镜头装到相机上，接着再把跟焦器套在金属管上，然后再将跟焦器的齿轮搭到镜头的齿轮上，最后启动跟焦器开始工作。整体安装过程比较繁琐，并且金属笼子本身体积较大，整体重量较大，在一些需要小体积、轻重量的场合中，例如使用手持云台或者无人机搭载相机进行拍摄时，就很可能出现不适用的情况，或者出现体积不合适安装不上去的情况。
