NEW OLD STOCK
49mm Rodenstock HR Digital MC Neutral density filter ND 0.9 / 8X (3 Stops) for reducing brightness, extending exposure time and intentionally reducing the depth of field by shooting at wide apertures in bright light.
Filter reduces light by 3 stops allowing for longer exposures or wide open apertures to be used in bright conditions.
Premium optical glass with perfect surface quality. Highly scratch-resistant. Neutral-tint, reducing the colour cast normally associated with ND filters.
