Used to select which light rays enter your camera lens Allows you to remove unwanted reflections from non-metallic surfaces Enables colors to become more saturated and appear clearer with better contrast The effect is often used to increase the contrast and saturation in blue skies and white clouds 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. Hardened Glass: Hardened optical glass that has 4 times the breaking strength in ANSI standardized testing (ANSI Z80.3 : 2001) where a steel balls of varying size and weight were dropped from a height of 50 inches onto the glass. High Transparency Polarizing Film; The polarizing film is the same as that used in the latest high definition LCD TV screens.

Could not be happier with this purchase. Recently used this lens while spending time at Whatcom Lake and it did above and beyond what I wanted from it. Made all shots involving water infinitely better than without, and with minimal light loss. The thin profile had no impact on wider lenses, which is a large bonus. The coating does wonders for keeping the lens protected; dealt with water spray and fumbling around on a moving boat. Very happy with this lens! ..
