B+W 77mm Linear Polarizer Filter

Product Highlights
  • Helps to Eliminate Reflections and Glare
  • Reduces Haze and Blue Cast in Landscapes
  • Greater Color and Tonal Saturation
  • Rugged Brass Filter Ring
  • High Quality Schott Glass

The B+W 77mm 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 polarizer only differs from a circular polarizer in that it does not contain a quarter wave plane that enables use of auto focus and exposure features. Linear polarizers are best suited for use with manual cameras, such as view cameras, that are not dependent on internal mechanisms to determine focus or metering settings.

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.

        'Poor' man's variable nutral density

            Comments about B+W 77mm Linear Polarizer Filter:

            Just like everyone else, I bought this to go with my circular polarizer (Hoya HD) to make a variable density ND filter because I just couldn't bring myself to shell out $$$ for something I won't use that often.
            Works like a charm from 2 to 7 stops.
            I marked the stops on the B+W edge to line up with the little triangle on the Hoya. Nice of them to put that there :)
            I was surprised that it only works when the liner is in front of the circular polarizer. I'm going have to break out the optics physics book and figure that one out.
            The only down side is that since both polarizers are made to rotate it is a little hard to hold the Hoya stationary and turn the B+W.
            Did I mention $ vs. $$$.
            Go for it!

                When matched with a good quality circular polarizer, this provides a reasonably priced home-made variable neutral density filter. If it was available in a thin mount, I would have rated it 5 stars.

                  I combined this linear filter with a circular polarizer and it creates a +/- 8 stop variable ND filter. Just like the Singh Ray product. Only about 1/3 the price.
