The super multi-coating is very effective at reducing lens flare and ghosting. Compared it to a friend's non coated polarizer and there was some drastic differences. The only complaint is that the filter does not have any outer thread. You would think that this should not matter much, but it means the lens cap can not be put back on while the filter is in place. Which means that if you are using it outdoors, you would have to make the choice between putting it in your bag uncapped, or taking the filter off each time you went to a new shooting location.

•Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens.
•They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc.
•They also saturate colors and increase contrast.
•Polarizers come in two variations but have the same effect. Linear polarizers work with older camera meters; Circurlar polarizers are designed for today's newer split-beam metering systems used in auto focus cameras. Check your camera's manual
•Extra thin filters are narrow construction with ultra thin glass. They are designed to avoid vignetting with today's larger wide angle lenses.
