NEUTRAL DENSITY FILTERS
Neutral density filters are designed to reduce the amount of light entering your camera lens and should not have any other effect on the image. Reducing the amount of light allows for the use of wider apertures or slower shutter speeds for creative and dramatic effect in bright lighting conditions.
HMC (HOYA MULTI COATED)
These popular filters are renowned for their ability to minimise reflection at the filter surfaces which reduces flare and ghosting. The result is an average light transmission of over 97%, giving sharp contrast and well balanced color. HOYA HMC filters are recommended for enhancing the performance of today’s multicoated lenses.
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:
