The Urth 40.5 mm Circular Polarizing (CPL) + ND64 lens filter is a high-quality screw filter specifically designed for photographers and videographers. With a diameter of 40.5 millimeters, this filter offers a versatile solution for enhancing image quality. The circular polarizing filter reduces unwanted reflections and improves color saturation, resulting in more vibrant and clearer images. Additionally, the ND64 filter allows for a reduction in the amount of light hitting the sensor, which is particularly useful for achieving longer exposure times or opening the aperture without risking overexposed shots. This filter is ideal for landscape and portrait photography as well as for shooting in bright light. The combination of CPL and ND64 functions makes this filter an essential tool for creative photographers looking to optimize their image composition. The filter is easy to handle and can be easily attached to various lenses, making it a practical addition to any photography kit.
