Heliopan 49mm Variable Gray ND Filter
Key Features
  • 0.3-1.8 Variable Neutral Density Filter
  • Increase Exposure by 1 to 6 Stops
  • Brass Ring Construction
  • High Quality Schott Glass
The Heliopan 49mm Variable Gray ND Filter is a solid variable neutral density filter providing a reduction of about 1 to 6 stops. The 0.3 to 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, allowing you to previsualize the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image.
