Description

一种相机镜头与滤镜的连接结构及相机滤镜和相机镜头 技术领域
本发明属于光学镜头技术领域，具体涉及一种相机镜头与滤镜的连接结构及相机滤镜和相机镜头。
背景技术
随着现代摄以技术的发展，多种多样的摄影技巧也相应出现，从而也产生了许多新颖独特的摄影艺术作品，随着艺术摄影的需要，为了满足摄影多种特效，开始出现了特质效果的滤镜。滤镜是安装在相机镜头前用于过滤自然光的附加镜头，是包括UV镜、偏光镜、减光镜、灰度镜、渐变镜、红外滤镜、星光镜、抗光害镜、柔光镜等多个镜头的组合，摄影者根据自己艺术创作的需要选择叠加的镜头种类和数量。
常规的滤镜镜头中的多个滤镜镜片采用螺纹连接的方式叠加，安装和拆卸比较费时，而且当多个滤镜拧在一起后，若操作不当还会出现拧死的情况。专利CN201721290691.9中所公开的磁吸滤镜结构中多个滤镜镜片之间通过通磁性吸附方式叠加，拆卸和安装十分方便。但是无论是螺纹连接的滤镜镜头，抑或是磁性吸附连接的镜头目前都存在一个不可难以避免的问题：即在摄影时，滤镜的连接框会部分挡住镜头而产生的摄影暗角。为了解决这个问题，有的做法是增大滤镜镜片直径，使滤镜镜片的直径大于相机镜头镜片的直径，这种方式虽然在一定程度上起到了减小暗角的作用，但是限于滤镜与镜头的安装方式，滤镜镜片的直径可以增加的幅度有限，不能从根本上解决摄影暗角的问题，尤其是广角镜头的摄像机，摄影的暗角问题目前都没有找到很好的解决的方式。
