Common polarizing filters are linear and may affect the AF and AE functions of digital camera this can be remedied by using circular polarizing filter therein the front part is a linear polarizing filter whereas the back part is a specific filter capable of rotating the light vibration plane of the polarized light passed through the front filter consequently not affecting the AE and AF functions.
偏振镜有线偏振镜和圆偏振镜之分,一般的偏振镜为线偏振镜,有可能影响数码相机的AE和AF功能,圆偏振镜的前部起偏振镜作用,通过特定振动方向的偏振光,其后面部分则能使该偏振光的振动方向在一个圆周上旋转,恢复为非偏振光,就不会影响相机的AE和AF功能了。
补充资料：偏振
横波的振动矢量(其方向垂直于波的传播方向)具有某一特定方向的现象。纵波的振动矢量方向沿着波的传播方向，所以不可能有偏振现象。
