Hoya 55 mm Neutral Density (ND) 0.6 Pro 1 Digital Multi-Coated Glass Filter

The Hoya 55 mm Neutral Density (ND) 0.6 Pro 1 Digital Multi-Coated Glass Filter has several uses, and offers the possibility to achieve otherwise unachievable results. ND filters appear grey, and reduce the amount of light reaching the film. They have no effect on color balance. Note! Pro 1 Digital filters are ultra thin, but have a front thread.

• 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)
