Hoya Digital Filter 77mm KIT 3 Filtri UV(c) + PL + NDx8

UV Filter

• Hoya filters provide additional benefits of correction for Ultraviolet(UV) light which can register on film and videotape as a bluish cast and can obscure distant details

• If desired they can be left on the lens at all times for protection

Circular Polarizer

• This filter eliminates ultraviolet rays to remove haze from outdoor shots as well as polarizing the light to remove reflections, and increase color saturation, without affecting the overall color balance

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 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)

Hoya Quality

• 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%
