LEE FILTER SW150 POLARIZER 150X150MM

LEE Filters 150 x 150mm SW150 Circular Polarizer Filter

150 x 150mm SW150 circular polarizing filter from LEE filters is compatible with a filter support LEE filters SW150-series and helps to reduce reflections and glare by filtering light that has been polarized due to the reflection of a non-metallic surface. Sunlight naturally becomes partially polarized due to the reflection of the electrons in the air molecules, causing the light to disperse in what appears as mist. A polarizing filter fixes, and filters, this directionally polarized light perpendicular to the reflected light, allowing the absorption of much of this light. This translates into a remarkable reduction in glare and reflections from non-metallic surfaces and an increase in saturation of the skies and foliage.

A circular polarizer differs only from a linear polarizer, since it contains a fourth wave plane, in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize linearly polarized light for the use of auto focus and exposure functions. Due to how light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy are skewed during use. When the light is circularly polarized, it allows the use of these functions.
This filter is not coated and is constructed from optical glass for clarity, as well as color fidelity. When the SW150 150 x 150mm circular polarizing filter is used, the desired degree of polarization is achieved by turning the filter holder on which it is placed.
It helps reduce reflections and glare by filtering light that has become polarized due to the reflection of a non-metallic surface.

The polarizing filters organize and filter directionally polarized light perpendicular to the reflected light, which allows the absorption of a large part of the light.
Clears the haze in distant landscapes and provides more saturated and vivid colors.
Stronger effect when used at a 90 ° angle from the sun.
Circular polarizers are ideal for use with digital cameras and autofocus lenses, where a linear polarizer often interrupts automatic exposure and focusing characteristics.
Not coated
The filter factor of 2.8 to 4x reduces the exposure by 1.5 to 2 stops.
Built from optical glass for clarity.
Metal filter case for storage and transport.
