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.
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.
