P.L & C.P.L 有乜唔同?

[zerochun]

PL鏡因為構造關係,所以用係唔適合用係自動對焦鏡頭,而cpl就無呢個問題,所以而時在場絕大部份都會係CPL

[Obi-Wan]

PL can be used in any digital camera WITHOUT a mirror to reflect the light ray to the AF sensor. BUT for SLR with AF system using ray reflected from the mirror, the mirror will cause turn the polarized light which will fool the AF system (and sometimes the exposure meter too) under certain lighting conditions. Circular PL solves this problem.

BUT I use a PL Sony A100 without any problem
