The Hoya Variable Neutral Density Filter provides a way to maintain exposure control by varying the amount of light entering the camera by 1.5 to 9 stops (0.45 to 2.7 density for cinematic use). The precision built-in double ring design allows the outer ring to rotate to control the amount of neutral density effect anywhere within the 1.5 – 9 stop range. This double-ring design is thin to reduce the likelihood of vignetting with wide-angle lenses.
The HOYA Variable Neutral Density filter can be used in place of several graded Neutral Density filters.
The Variable Neutral Density filter is helpful when:
Original . . .
Hoya engineers have developed a new ANTISTATIC coating that acts like a force field around the filter to repel dust. Perfect for environments where dust is common, these filters require less frequent cleaning and maintenance than traditional filters. Additionally, the hardened, antistatic top-layer is water repellent, stain and scratch resistant, and cleans easily when smudges or fingerprints are introduced to the surface. The filter’s UV properties filter unwanted ultra-violet rays, reducing haze and increasing clarity.
The new FUSION Antistatic professional filters are made in Japan using hand selected silicates that are carefully smelted and blended to yield high performance optical glass. Hoya then uses extreme care and precision to apply the improved 9-layer Super Multi-coating formula which greatly reduces or eliminates reflections on the surface of the glass and yields an ultra clear high transmission rate. This means the filter has virtually no effect on the colour balance, contrast, or clarity of the final image.
The filters features a lightweight, one-piece, low-profile aluminum frame to house the glass. This one-piece design allows the filter to maintain perfect parallel alignment to the sensor plane for maximum sharpness, while the low-profile form eliminates vignetting when used on ultra-wide-angle lenses.
