Overview

Overview

The B&W 77mm Kaeseman Circular Polarizing Multi-Resistant Coating (MRC) Glass Filter (Slim) is constructed from select polarizer foils and especially prepared optical glass. Kaeseman ("encased") filters are completely edge-sealed for maximum durability under extreme climatic conditions.

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 varied by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.

B&W slim filters are for wide-angle lenses and are 3mm thick. They do not have a front thread.

  • This filter eliminates ultraviolet rays to remove haze from outdoor shots as well as polarizing the light to remove reflections, and increase color saturation, without affecting the overall color balance
  • This filter is especially effective in areas of great temperature and humidity extremes
  • Use it indoors (museums, galleries) and outdoors
  • Effective for making a blue sky bluer, making clouds stand out or increasing (or decreasing) the color saturation of water
