Hoya Variable Neutral Density Filter 55mm

Hoya 55mm Variable Neutral Density Filter

The Hoya 55mm 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, especially 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.
• Use wider apertures to reduce depth of field and emphasize 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 Optical Quality

The filter is made from high-quality optical glass to maintain image clarity. It is housed in a slim-profile aluminum ring designed to reduce vignetting on wide-angle lenses. The filter does not have front accessory threads.
