I bought the Tiffen TICP77 77mm Circular Polarizing Filter and it's pretty much useless. $70 wasted, can spin that thing all day long and can't see the difference. It also knocks off a little over a full stop of light. I would read up on the reviews for what specific models you are interested in. BH usually has the most, just filter out (excuse the pun) the blah blah blah reviews from people just posting to qualify for the write a review promotions.
