Hoya 40.5mm Circular
Polarizer Slim Filter: Hoya 40.5mm 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 plane 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 40.5mm filters.
The filter
protects front
lens surface from scratches, moisture, dirt and other accidental damages.

The Hoya 40.5mm 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.
A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter.
The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions.
Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use.
When the light becomes circularly polarized, it permits the use of these functions.
