The Urth 86mm ND8 128 (3 7 Stop) Variable ND Lens Filter is a high-quality screw filter specifically designed for photographers and videographers who desire precise control over the exposure of their shots. With a diameter of 86 millimetres, this filter is suitable for a variety of lenses and allows for the reduction of the amount of light hitting the sensor. The ND filter (Neutral Density) offers a variable density of 3 to 7 stops, enabling flexible adjustments to different lighting conditions. This is particularly useful when shooting in bright environments, where overexposure needs to be avoided. The filter helps control depth of field and achieve creative effects by allowing longer exposure times in daylight. Its robust construction and high-quality optics ensure even light distribution and minimise unwanted reflections. The Urth ND filter is therefore an essential tool for anyone looking to enhance their photographic and filmmaking skills.
