Product Highlights
  • Helps to Eliminate Reflections and Glare
  • Reduces Haze and Blue Cast in Landscapes
  • Greater Color and Tonal Saturation
  • Slim-Line Mount for Wide Angle Lenses
  • Lightweight Aluminum Filter Ring
  • High Quality Schott Glass

The B+W 55mm Circular Polarizer Slim 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. 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 dependent on your specific lens and how thick the front rim of the lens is; with thinner, low-profile lenses usually being affected more.

              It's always good to have an extra battery around. And the polarizing filter is great for those bright days.

              B&W makes great filters and for around $50 for a good slim CPL you can't go wrong. *** The lighter the weight with this the slim line of filters on the market is definitely a +++.

                Filter is very good. However, the Sony lens cap will not snap onto the filter. Possibly a weakness in all slim filters? I don't know. But obviously an inconvenience to have to unscrew the filter everytime you want to put the lens cap back on.
