which brand is the best????

[老叟]

sorry, the answer is "no"!!!
the expensive isn't the best,
the cheap isn't bad!!!

If you believe that the most expensive or famous must be the best, buy B+W MRC. Otherwise, get yourself a HOYA HMC SUPER UV(0).

最簡單，放在白紙上看，自已選吧

[Gowest]

There is no such thing as "the best" to your question, which is neither measurable nor quantifiable.總之唔係買雜牌就得啦

Doesn't work that way. UV filter is not actually colourless.
