Formatt Hitech BF 39CP2000RH overview

  • 1Description

The Formatt Hitech 39mm Glass 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.

This filter is constructed from Schott B270 Glass for increased clarity as well as color fidelity and features an aluminum-alloy filter ring that can be rotated in order to adjust the intensity of the polarization effect. To reduce the possibility of vignetting while using Formatt Hitech 39mm Glass Circular Polarizer Filter, the filter ring's front diameter is slightly larger than the rear diameter. This may prevent the use of some lens manufacturer bayonet hoods.

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
Clears up haze in distant landscapes and provides more saturated, vivid colors.
Strongest 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 will often disrupt auto exposure and focus features.
2x filter factor reduces exposure by 1 stop.
Non-coated.
Aluminum-alloy filter ring for durability while remaining lightweight.
Filter ring does not feature front filter threads and can be rotated to adjust the intensity of the polarization effect.
Constructed from Schott B270 glass for optical clarity.
Flannelette pouch for storage and transport.
