I am also looking for a polariser. I am not really after those multi coated ones. So a normal one will do. Went to check the prices. For the 77mm filter thread, the kenko is $40+ while the hoya is $80+ for a normal one. Anyone knows why is there such a great price difference as both are single coated? Heard there is a Tokina one, but i do not know the price for 77mm. Any kenko polariser users? What are your experience? How is this filter? Serve its purpose well?
