Tiffen 4.5" Round Combination 85 and Circular Ultra Polarizing Filter

Circular Ultra Polarizer
If a traditional polarizer doesn't give you enough "zip", the Tiffen "Ultra" polarizer gives you a little more. Ultra Polarizers bump up your blue skies a touch more just enough to make that critical difference. Tiffen Linear Ultra Pol and Circular Ultra Pol filters offer the best polarization effects available for professional motion picture and television work. They extract the maximum of unwanted glare from the scene and render crisp white clouds against a dramatically dark blue sky, like never before.
