Hoya 40.5mm CIRC-POL Pro1D DMC Filter

The HOYA 40.5mm CIRC-POL Pro1D DMC Filter 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. Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting. Key Features of the HOYA 40.5mm CIRC-POL Pro1D DMC Filter Allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. Saturate colors and increase contrast - often used to increase the contrast and saturation in blue skies and white clouds Hoya's Polarizing filters do not affect the overall color balance of a shot 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 MPN - C559340 GTIN - 024066059161
