Hoya 72mm Circular Polarising Filter - Pro HD
Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camera lens. PL (Linear Polarising) and CIR-PL (Circular Polarising) filters have the same effect, but it is important that you choose the correct version for your camera. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer, with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. HOYA's polarising filters do not affect the overall color balance of a shot.
How to select the correct Polarising filter
Many of today's cameras use semi-silvered mirrors or prisms to split the light entering the viewfinder in order to calculate exposure and focusing distance. PL (Linear Polarising) filters can sometimes interact with these items to give unpredictable exposure or focusing. So we recommend that you choose a CIR-PL filter unless you have a manual focus camera which has no beam splitter.
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. It has 25% higher light transmission than standard polarizing film used in current photographic filters.
Waterproof / Scratch & Stain Resistant Multi-Coating
Specialized coatings that are not just water-proof to repel water spots but also hardened to be scratch and stain resistant. Of course these coatings are from HOYA so they are greatly reduce reflections off the surface of the glass allowing you to capture more light in your photos.
