The Urth 55mm ND16 (4 Stop) lens filter is a high-quality screw-on filter designed specifically for photographers and videographers who seek precise control over their exposure. With a filter diameter of 55 millimeters, this neutral density filter is ideal for a variety of lenses. The ND16 filter reduces the amount of light hitting the sensor by four stops, allowing for longer exposure times or a wider aperture in bright lighting conditions without overexposing the images. This is particularly useful for creating smooth motion blur in water or clouds, as well as achieving a pleasing background blur. The filter is made from high-quality materials to ensure optimal image quality while minimizing reflections and color distortions. The Urth 55mm ND16 (4 Stop) lens filter is therefore an essential tool for creative photographers looking to expand their image-making capabilities.
