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 colours 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 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 filters greatly reduce the appearance of lens flare and ghosting caused by reflections
Filters feature a black matte aluminium satin finish Almite frame which reduces reflections
These filters are equipped with black rimmed glass to reduce the chance of light reflecting off the edge
Ultra-thin filter frames to help avoid vignetting on super wide-angle lenses are also designed to hold a lens cap
These filters are equipped with a straight knurling edge for non-slip, easy attachment and removal
Filter cases are UV protected to further lengthen the life of filters
