Description

The NiSi 4 x 4" Linear 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 linear polariser differs from a circular polariser in that it does not contain an additional quarter wave plane. The addition of a quarter wave plane is to circularly polarise linearly polarised light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polariser, in-camera auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarised, it permits the use of these functions.

This filter is recommended when not using in-camera exposure metering or autofocus. It is made using a process that involves laminating a layer of polarising film between 2 pieces of optical glass. The glass layers are then ground flat to maintain image sharpness.

Key Features:

  • Helps to reduce reflections and glare by filtering out light that has become polarised due to reflection from a non-metallic surface.
  • Polarising filters arrange, and filter, directionally polarised 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 colours.
  • Strongest effect when used at a 90° angle from the sun.
  • Recommended when not using in-camera exposure metering or autofocus.
  • Non-coated.
  • 2 to 2.8x filter factor reduces exposure by +1 to 1.5 stops.
  • Constructed using optical glass for clarity.
  • Leatherette pouch included for storage and transport.
