Overview

Helps to Eliminate Reflections and Glare, High Quality Schott Glass

Description

The B+W 62mm Circular Polariser Slim Filter helps to reduce reflections and glare by filtering out light that has become polarised due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarised due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarising filter arranges, and filters, this directionally polarised 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 polariser only differs from a linear polariser in that it contains a quarter wave plane in addition to the linear polarising filter. The addition of this quarter wave plane is to circularly polarise the 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, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarised, it permits the use of these functions.

B+W filters are constructed from high quality Schott glass for increased optical clarity and colour fidelity. The slim filters are specifically designed for use with wide angle lenses and are only 0.2" / 5mm thick. They do not have front threads for stacking additional filters.

Note: This filter ring's outside diameter is slightly larger than the actual thread size, and because of this you may be unable to attach the lens manufacturer's bayonet-mounted lens hood to the lens while using this filter. This is dependant on your specific lens and how thick the front rim of the lens is; with thinner, low-profile lenses usually being affected more.

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° from the sun.
  • Circular polarisers are ideal for use with digital cameras and autofocus lenses where a linear polariser will often disrupt auto exposure and focus features.
  • Constructed from high quality Schott glass for optical clarity.
  • Lightweight, slim aluminium filter ring measures 5mm thick to help reduce vignetting.
