The Hoya Pro 1 Digital Circular Polarizer takes advantage of Hoya's patented optical glass technology to create a hardened glass that is thinner than the normal optical glass. This allows the overall thickness of the filter to be reduced to avoid vignetting when used with ultra-wide angle lenses.

Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.

• Digital Cameras Need Multicoated Filters

Digital camera CCD or CMOS sensors are highly susceptible to reflections - this stray light can ruin your photographs! Don't risk your valuable photos by using bare-glass filters

• Digital Multi-Coated

Digital multi-coated filters greatly reduce the appearance of lens flare and ghosting caused by reflections

• Black Almite Frame

Filters feature a black matte aluminum satin finish Almite frame which reduces reflections

• Black Rimmed Glass

These filters are equipped with black rimmed glass to reduce the chance of light reflecting off the edge

• Low Profile Frame

Ultra thin filter frames to help avoid vignetting on super wide angle lenses are also designed to hold a lens cap

• Knurling Edge Frame

These filters are equipped with a straight knurling edge for non-slip, easy attachment and removal

• UV Protected Case

Filter cases are UV protected to further lengthen the life of filters

Polarizing filters do not affect the overall color balance of a shot
