I need a cheap CPL filter to learn how to shoot with it.
Can recommend a relatively ok quality one that is reasonably priced? Budget about $50.
I saw in mass sale, screw in 77mm Tianya CPL filter only costs $35, but read also that QC is very bad.
The price guide, http://www.clubsnap.com/forums/showthread.php?t=263716, also has Hoya 77mm CPL at $70 and Tokina 77mm CPL at $45, but I don't know how updated is the price.
