The Tiffen 4 x 5.65" Ultra Linear Polarizing Filter is a filter that lets you take photos that would ordinarily be impossible to achieve. Tiffen Ultra Circular Polarizing filter is good when 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.
This filter offers 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.
