Hoya 67mm Neutral Density (ND) 0.6 Pro 1 Digital Multi-Coated Glass Filter

Digital Multi-Coated

Digital multi-coated filters greatly reduce the appearance of lens flare and ghosting caused by reflections

Black Almite Frame

Filters feature a black matte aluminum, satin-finish almite frame, which reduces reflections

Black Rimmed Glass

These filters are equipped with black-rimmed glass to reduce the chance of light reflecting off the edge

Low Profile Frame

Ultra-thin filter frames, which help to avoid vignetting on super wide angle lenses, are also designed to hold a lens cap

Knurling Edge Frame

These filters are equipped with a straight knurling edge for non-slip, easy attachment and removal

UV Protected Case

Filter cases are UV protected, which further lengthens the life of filters

Neutral Density Filters have four main uses:

• To enable slow shutter speeds to be used, especially with high-speed films, to record movement in subjects such as waterfalls, clouds, or cars
•  To decrease depth-of-field by allowing wider apertures to be used, which helps to separate subjects from their background
• To decrease the effective ISO of high-speed film (above ISO 400), and allow it to be used outdoors in bright situations
• To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes, which could cause overexposure

Neutral Density Factors

• 2x = ND 0.3 (exposure adjustment = 1 stop, reduces ISO 1/2)
• 4x = ND 0.6 (exposure adjustment = 2 stops, reduces ISO 1/4)
• 8x = ND 0.9 (exposure adjustment = 3 stops, reduces ISO 1/8)
