Product Highlights
This B+W Neutral Density Filter reduces the light by six f-stops. With this filter and without changing the f-stop, a shutter speed of 1/60 s is changed to a full second, thus requiring the use of a tripod.

Overview

Neutral Density Series

ND filters evenly reduce the transmittance of light over the entire VIS spectrum. They decrease the brightness of an image without changing the depth of field (DoF). They attenuate light by absorbing a part of the energy of the VIS wavelength, without influence on the color balance. ND filters are used to control the intensity of light going through an optical system to avoid overexposure, blooming on imaging sensors and prevent damages on light sensitive measuring sensors. ND filters are available mounted with common thread sizes M 25.5 to M 67 and unmounted in sizes 27 mm to 74 mm diameter. Intermediate size down to 10 mm possible on request.

Key Features:

  • Insensitive to angle of incidence
  • Decrease brightness without changing depth of field
  • Stackable, combine ND filters to achieve OD needed
  • Even attenuate avoid effects on color balance

B&W Neutral Density filters are available in the following strengths:

  • 1010.3 (2x) Reduces light 1x stop
  • 1020.6 (4x) Reduces light 2x stops
  • 1030.9 (8x) Reduces light 3x stops
  • 1061.8 (64x) Reduces light 6x stops
  • 1103.0 (1,000x) Reduces light 10x stops
  • 1134.0 (10,000x) Reduces light 17x stops (ideal for astrological and sun studies)
