Hoya 37 mm Neutral Density (ND) 0.6 Hoya Multi-Coated (HMC) Glass Filter

The Hoya 37 mm Neutral Density (ND) 0.6 Hoya Multi-Coated (HMC) 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. Multi-coated to minimize reflection at the filter surfaces which reduces flare and ghosting.

Neutral Density filters have four main uses

• To decrease depth of field by allowing wider apertures to be used, which helps 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.3 (exposure adjustment = 1 stop, reduces ISO 1/2)

• 4x = ND.6 (exposure adjustment = 2 stops, reduces ISO 1/4)

• 8x = ND.9 (exposure adjustment = 3 stops, reduces ISO 1/8)

• As one of the premier filter manufacturers, Hoya filters continue to made from quality glass assuring the photographer clear, sharp and accurate images

• Hoya filters consistently provide even color all the way through the filter; All surfaces are ground and polished to specific thickness and tolerances

• Even non-multi-coated Hoya filters have one layer of anti-reflective coating applied to each surface of the glass; Hoya's single layer coating decreases light reflection off the surface from approx. 9% to an average of 4-5%
