Hoya HRT 49mm Circular
Polarizing + UV Filters: Features - Hoya HRT 49mm Circular Polarizing + UV Filter Specification - Hoya HRT 49mm Circular Polarizing + UV Filter Kit Content
Hoya HRT 49mm Circular Polarizing filter is a lightweight and durable filter
that is designed to block ultraviolet light and reduce the bluish cast of
daylight while also helping to eliminate reflections and glare by filtering out
light that has become polarized due to reflection from a non-metallic surface.
The light from the sun naturally becomes partially polarized due to reflecting
off electrons in air molecules, causing the light to scatter into what appears
as haze. A filter with polarizing capability arranges, and filters, this
directionally polarized light perpendicularly to the reflected light, allowing
for the absorption of much of this light. This results in a noticeable reduction
of glare and reflections from non-metallic surfaces and an increase in the
saturation of skies and foliage. This circular polarizer is ideal for use with
digital cameras and autofocus lenses where a linear polarizer will often disrupt
auto exposure and focus features. It is ideal to use for photographing nature
and outdoor shooting
