Hoya 43mm Circular Polarizer Slim Filter is a lightweight and durable filter which is designed for digital camera. This Hoya Circular Polarizer filter helps to reduce 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 polarizing filter 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 Hoya filter has an 8-layers multi-coating for very high average light transmission of 99.35%. It is constructed from optical glass and features a thin frame. A circular polarizer only differs from a linear polarizer in that it contains a quarter wave planes in addition to the linear polarizing filter.
The polarizer filter enables colours to become more saturated and appear clearer with better contrast. It is ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features. It clear up haze in distant landscapes and provides more saturated, vivid colours. The filter is ideal for capturing nature, travelling, outdoor, landscape and marine photography. It is compatible with lenses that are threaded for 43mm filters. The filter protects front lens surface from scratches, moisture, dirt and other accidental damages.
