• Variable filter for specific reduction of the amount of light
• Possibility to lengthen the exposure time between +1 and +8 (ND2-400) aperture stops
• Rotary mount for individual adjustment
• Coating: one layer on each side
• Quality standard (glass): high-quality lens glass
  
  Impact on the pictures:
• Allows large apertures e.g. when shooting portraits when it is extremely bright: due to a blurred background the photographed person is clearly visible in the foreground
• Due to long exposure times flowing water gets "soft"
• Creates an impressionistic flair in poor light conditions

• 1 Vario neutral-density filter
• 1 filter box

To avoid vignetting, this filter has a superstructure of the front lens, i.e. the diameter of the front lens is larger than that of the rear lens. Please note that a lens cap with 55 mm is thus required.
