The 40.5 mm Circular Polarising (CPL) lens filter from Urth is a high-quality polarisation filter specifically designed for use with cameras. This screw filter allows photographers to reduce light reflections on non-metallic surfaces and enhance colour saturation, resulting in more vibrant and clearer images. The filter is particularly useful for landscape photography, as it makes the sky appear more intense and improves the visibility of clouds. Additionally, the CPL filter can be used when capturing water surfaces to minimise unwanted reflections. The filter is easily mounted by screwing it onto the lens, ensuring user-friendly handling. With its robust construction and high optical quality, the Urth 40.5 mm CPL filter is a valuable addition to the equipment of photography enthusiasts looking to expand their creative possibilities.
