Hoya
72mm Variable Neutral Density 3-400 Filter

The Hoya 72mm Variable Neutral Density Filter is a solid variable neutral density filter providing an exposure reduction of about 1.5 to 9 stops. The 0.45 to 2.7 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than would normally be required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine 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. This filter is constructed from optical glass to maintain image clarity and is set within a slim profile aluminum ring, which helps to reduce the likelihood of vignetting when used on wide-angle lenses, and does not feature front threads.

• Variable neutral density filter allows you to dial in differing amounts of density from scene to scene

• 0.45 to 2.7 density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required

• Providing a reduction of 1.5 to 9 stops, this filter allows you to control depth of field and convey movement more easily

• Slim profile filter ring helps to reduce the likelihood of vignetting with wide-angle lenses.

• Possible to shoot with fast lenses like a 50mm f/1.4 lens wide open in full sun for a very shallow depth of field. Or, to slow down the shutter speed to where the shutter can be open for several seconds in full sunlight.
