The Hoya Variable Neutral Density Filter offers an effect similar to that of a standard neutral density filter, but it uses two polarizing layers to control the amount of light that passes through the filter and into the camera lens. It can be adjusted from ND3 to ND400. This Hoya ND filter can darken the scene by anywhere from 1.5 to 9 EV. The filter allows the use of wide apertures while keeping the correct exposure within the shutter speed range of your camera, or of very long shutter times to emphasise motion.
When the filter is mounted on the lens, turning the filter ring between 'Min' and 'Max' can greatly control the amount of light entering the lens. With the Hoya Variable Neutral Density Filter it is possible to shoot with fast lenses like a 50mm f/1.4 lens wide open at f/1.4 in full sun for a very shallow depth of field. Or, to slow down the shutter speed to where the shutter can be open for several seconds in full sunlight. This is enough to create artistic blurring shots of motion on water, cars, people or almost anything that moves. The creative possibilities are endless. The practical exposure range and light transmission will vary depending on the situation. When using the filter near or at ‘Min’, a cross-like dark pattern may appear across the image. This is a property of variable ND filters.
This Hoya Variable Density Filter uses high-quality optical glass from Hoya Corporation, the worlds largest optical glass manufacturer and is available in sizes 52mm to 82mm.
