I found the result of CPL is different depending on the brand.

Is there anybody interest to discuss about them, such as B+W, Hoya, Kenko, Canon and Nikon.

I am awared the Nikon will cost 980.00
B+W costs450.00
Hoya costs 280.00
Kenko costs 350.00
Canon costs 650.00?
(price may not be exactly true. just about)
