大部分镜头在前端都有滤镜螺纹接口，可以安装各种滤镜。这些滤镜可以实现各种效果，比如为场景增加色彩，帮助压暗场景，增加特殊效果以及其他等等。

滤镜接口

不同的镜头有不同的滤镜接口。通常接口尺寸会标注在镜头前端或镜筒上。找到类似Ø=67mm这样的标识，那就是滤镜尺寸。

方形滤镜

有一种滤镜是“插入式”的方形滤镜，而不是常见的圆形。它的好处是不用为不同尺寸的镜头购买单独的滤镜，只需要更换不同的滤镜座，就可以使用同一套滤镜。

用滤镜保护镜头

很多摄影师会在镜头前装一片天光镜或UV镜来保护镜头。因为滤镜比镜头便宜得多，也更容易更换。

使用滤镜会对画质造成轻微的损失。这是一个有关成本/收益的问题：你是否愿意牺牲一点画质来换取。相反，你也可能认为这样做不值得。
