Tiffen 55ND9 55mm Neutral Density 0.9 Filter

The Tiffen 55ND9 is a 55mm neutral density filter that reduces the light reaching your sensor or film by exactly three stops (0.9 density). This controlled reduction lets you open up your aperture for a shallower depth of field in bright sunlight, extend shutter speeds to capture motion blur in waterfalls or traffic, or simply balance an exposure that would otherwise blow out highlights. Because the filter is spectrally neutral, it dims the light without introducing a color cast, keeping your whites clean and your color grading consistent.

Built by Tiffen, a manufacturer with decades of experience in optical filters, the 55ND9 uses precision-ground glass in a slim metal ring that threads directly onto any 55mm lens. It works equally well with color film, black-and-white film, and digital sensors, so it remains useful no matter how your gear evolves. Whether you are shooting portraits wide open at midday or slowing your shutter for a silky waterscape, this filter provides a reliable, repeatable three-stop reduction every time you screw it on.
