B+W 40.5mm Circular Polarizer Filter - Schott Glass - Silver Box - 65-075312-OS

  • $ 4995


  • 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 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. Features a single anti-reflection coating per side to help prevent ghosting and reflections as well as increase light transmission from approximately 92% (uncoated glass) to over 98%.
  • Constructed from high quality Schott glass for optical clarity. Brass filter ring helps to prevent jamming and provides additional strength.
  • Plastic case included for storage and transport.


This item is an older non F-Pro series Filter. Same Standard SC coated product. Exposed filter ring depth of this filter is 8mm B&W Circular Polarizer Glass Filter - Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun. Note! Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems without problems). Effective with cameras that use beam splitters in the path of the TTL light meter and with AF cameras High light transmission characteristics Produce good shadow detail Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
