Schneider 4.5x22 Mounted True-Pol Circular Polarizer Filter 68-013145

Description

Schneider Mounted Circular Polarizer Filter, For Third-Party or Custom Holders, 2.97x Filter Factor, +1.57 Stops, Helps to Eliminate Reflections and Glare, Reduces Haze in Landscapes, Greater Color and Tonal Saturation, Non-Coated, Water White Optical Glass, 4.5" Filter Ring, Mount, Filter Pouch. 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. Schneider Mounted Circular Polarizer Filter, For Third-Party or Custom Holders, 2.97x Filter Factor, +1.57 Stops, Helps to Eliminate Reflections and Glare, Reduces Haze in Landscapes, Greater Color and Tonal Saturation, Non-Coated, Water. Constructed from Water White optical glass this 4.5 filter is mounted for use in third-party or custom filter holders. Schneider Mounted Circular Polarizer Filter, For Third-Party or Custom Holders, 2.97x Filter Factor, +1.57 Stops, Helps to Eliminate Reflections and Glare, Reduces Haze in Landscapes, Greater Color and Tonal Saturation, Non-Coated, Water White Optical Glass. 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. This filter is non-coated and delivers approximately 33% average light transmission.

Key Features

• The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions.
• Schneider Mounted Circular Polarizer Filter, For Third-Party or Custom Holders, 2.97x Filter Factor, +1.57 Stops, Helps to Eliminate Reflections and Glare, Reduces Haze in Landscapes, Greater Color and Tonal Saturation, Non-Coated, Water.
• A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter.
• 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.
• Constructed from Water White optical glass this 4.5 filter is mounted for use in third-party or custom filter holders.
