Hoya Variable Neutral Density Filter 72mm

Hoya 72mm Variable Neutral Density Filter

The Hoya 72 mm Variable Neutral Density (ND) Filter offers precise exposure control by varying the light entering the camera from 1.5 to 9 stops (0.45 to 2.7 density for cine use). Its precision-built double ring design allows the outer ring to rotate, adjusting the neutral density effect smoothly within this range. The slim double-ring construction minimizes vignetting when used with wide-angle lenses.

Key Features and Uses

• Control depth of field by enabling wider apertures.
• Create or manage motion blur by selecting slower shutter speeds for perfect blurring effects.
• Replace multiple graded ND filters, saving cost and time by adjusting the effect with a simple rotation.
• Slow shutter speeds for motion blur effects such as waterfalls, moving vehicles, or panning shots to emphasize the subject.
• Use wider apertures to reduce depth of field and focus attention on the subject.
• Enable higher ISO films or sensors in bright lighting conditions.
• Allow cine/video cameras with fixed shutter speeds to film in bright environments like beaches or snowy scenes.

Construction and Specifications

The filter is made from high-quality optical glass to maintain image clarity and is housed in a slim-profile aluminum ring to reduce vignetting risks. It does not feature front accessory threads.
