除保護鏡外, 如你所述, 偏光鏡是少不了的, 買塊CPL吧, 藍天白雲靚景靠晒佢, 有時用黎減光都可以, DSLR有WB可較, 彩色攝影用的矯色濾鏡完全不需考慮, 其他特效濾鏡你自己決定好了。

偏光鏡有線性偏光鏡及環形偏光鏡(CPL)兩種，使用方法一樣。使用單鏡反光機時，因為相機內使用了一片反光鏡片，環形偏光鏡可以確保對焦的準確性。如果在一般數碼相機使用的話，由於數碼相機沒有反光鏡片，使用較便宜的線性偏光鏡可獲得相同效果。

if you have more budget, you can buy a nikon's or cannon's.

ckmb:

not only consider the price, size is another problem.

You probably don't need polarizer all the time you tale photo, so one good CPL is all you need for all your lens.

If you don't need to use CPL very often, you'd better buy a bigger one as a big filter can always use on a smaller lens.

However, don't use a adaptor ring to attach CPL on ultra wide angle lens as the filter itself is already too thick, with the adaptor ring, the filter edge may affect final image.

Unless you want to cut out refection from a refelctive surface at a particular angle, THERE IS NO USE AND WASTE YOUR MONEY ON SPENDING A POLARIZED FILTER ON 50 MM LENS.

EVERY OTHER PPL SHOULD ONLY PAY ATTENTION TO PROESSIONAL OPINION.

嘩, 又黎一個"大師". 原來PL鏡淨係為左唔要REFLECTION, 真係唔講唔知呀.

[john1333]

if you can a substanial difference with a Polarizer filter use on "50 mm lens" with other purposes than reducing reflection.

PLS LET ME KNOW!!!!
