  • Helps to Eliminate Reflections and Glare
  • Reduces Haze and Blue Cast in Landscapes
  • Greater Color and Tonal Saturation
  • Single Anti-Reflection Coating
  • Rugged Brass Filter Ring
  • High Quality Schott Glass

The B+W 46mm Circular Polarizer SC 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.

B+W filters are constructed from high quality Schott glass for increased optical clarity and color fidelity. They feature a brass filter ring for durability as well as jamming prevention. This filter is vacuum coated with 1 layer of anti-reflection coating per side to help prevent internal ghosting and reflections as well as improve light transmission.

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.

    Comments about B+W 46mm Circular Polarizer SC Filter:

    I bought the B&W Circular Polarizer to mount on my new Leica DG Macro-Elmarit f2.8 45mm aspherical lens, mostly used for macro shots of insects, flowers and "things", as well as "skyscapes" and portraiture. In a week of use I have found it to be totally up to spec and reputation. It rotates beautifully smoothly — much more so than cheaper circular polarizers I have used on other lenses — and adds greatly to colour saturation and vibrant contrast in clouds. A must-have for my kind of photography. I started using B&W filters 30+ years ago with lenses on my M3 and CL Leicas and found them to be totally dependable. Nice to know this quality is still available in the digital age. Worth the price for using with top-end glassware.
