The Urth 37mm ND8 (3 Stop) lens filter is a high-quality screw filter designed specifically for photographers and videographers who seek precise control over the exposure of their shots. With a diameter of 37 millimeters, this neutral density filter is ideal for a variety of lenses and allows for a reduction of light hitting the sensor by three stops. This is particularly useful in bright environments where overexposure needs to be avoided. The ND8 filter helps achieve longer exposure times, enabling creative effects such as motion blur in water or clouds. Additionally, it allows for a wider aperture during daylight, resulting in a shallower depth of field. The filter is made from durable materials that ensure high optical clarity while protecting against dust and scratches. The Urth 37mm ND8 lens filter is thus an essential tool for anyone looking to expand their photographic capabilities.
