HOYA CIR-PL HD Nano 82mm

HOYA CIR-PL HD Nano 82mm

Circular polarizing filter.
Polarizing filters filter out unwanted reflections from non-metallic surfaces such as water and glass as well as light that is reflected off moisture and pollution in the atmosphere, which is how they can create  beautiful deep blue skies. You can seen the effect happening before your eyes as you rotate the filter. In addition to bluer skies, the filter reduces reflections, yields greener foliage in scenery and better clarity and contrast in your pictures.

The HD Nano CIR-PL filter is using high transmission polarizing film, creates a picture that can be recognized clearly by a better contrast and clarity. This effect enables a fast shutter speeds. The filter will not affect the overall color balance of the shot
High transparency polarizing film has 25% better light transmission than standard polarizing film used in current photographic filters. This translates to nearly 1/2 stop more light entering the lens while yielding the same polarization effect, maintain color balance of a standard circular polarizer while improving contrast and clarity.

HD Nano CIR-PL coatings have the advantage of being the hardest, scratch & stain resistant coatings available from any manufacturer. Over time normal filter coatings can be easily damaged by repeated cleanings by wiping with too much force or abrasive cleaning cloths.
The HD Nano coating is 200% harder for increased longevity and greater protection.
