The Hoya 72mm Digital Filter Kit IIincludes a UV (C) HMC filter a circular polarizer filter and a 3-stopneutral density filter in a convenient filter pouch. This kit provideseverything necessary to get started with filtration for your digitalcamera. The UV (C) filter is a multi-coated filter with a slimmounting ring. This makes it useful for wide-angle lenses to avoidpotential vignetting. Also the UV filter itself is a general use clearfilter that helps to absorb ultraviolet light. No additional colorationor contrast is provided allowing you to pair this filter with others.It is also useful as a general protective filter to leave on lenses atall times. Filters help to reduce dust and moisture from reaching yourlens element and provide additional protection in case of drops orsituations where scratching could occur. Hoya HMC filters aremulti-coated for reducing flare ghosting and reflections on the filtersurface. As a result over 97% light transmission is possible providing you with additional contrast and high color fidelity. A circular polarizer filter helps to reduce reflections and glare byfiltering out light that has become polarized due to reflection from anon-metallic surface. The light from the sun naturally becomes partiallypolarized due to reflecting off electrons in air molecules causing thelight to scatter into what appears as haze. A polarizing filterarranges and filters this directionally polarized lightperpendicularly to the reflected light allowing for the absorption ofmuch of this light. This results in a noticeable reduction of glare andreflections from non-metallic surfaces and an increase in the saturationof skies and foliage. A circular polarizer only differs from alinear polarizer in that it contains a quarter wave plane in addition tothe linear polarizing filter. The addition of this quarter wave planeis to circularly polarize the linearly polarized light for the use ofauto focus and exposure functions. Due to how the light is broken downand filtered with a linear polarizer auto focus and exposure accuracybecome skewed during use. When the light becomes circularly polarized it permits the use of these functions. A neutral density filterhas several uses and offers the possibility to achieve otherwiseunachievable results. ND filters appear gray and reduce the amount oflight reaching the film. They have no effect on color balance. Thisfilter offers a filter factor of 0.9 equivalent to 3 stops of light.
