i think this filter cost about 10SGD?
Hmm i saw some filters on mass sales selling for over 100!
now im confused which is the type of filters i wanted..
hahaha
Like buying a car part, you can either quality or slightly lesser quality product. If you want to experiment first, get the $10 version first. Then invest in a good one. Else, if you don't have time to do it, go ahead for the >$100 CPL filter.
In the end, its all a matter of quality result you want.
