The filter is designed with a diameter of 40.5 millimeters, making it compatible with a variety of lenses that support this size. The ND64 filter is ideal for long exposures to create motion blur, as well as for use in video recording to optimize shutter speed. The construction of the filter ensures high optical clarity and minimizes unwanted reflections, resulting in improved image quality. The Urth 40.5mm ND64 (6 Stop) lens filter is thus an essential tool for creative image makers looking to expand their photographic possibilities.
