The Urth 55mm Base Filter Kit Pro (UV CPL) is a comprehensive filter set for photographers seeking enhanced image quality and lens protection. This kit includes a UV filter that blocks ultraviolet light to reduce haze and protect the front lens elements from scratches, dust, and moisture, as well as a circular polarizing filter (CPL) that minimizes reflections from non-metallic surfaces like water and glass while enhancing color saturation and contrast. Both filters feature a 55mm thread, ensuring compatibility with a wide range of camera lenses, and are made from high-quality optical glass with multi-layer coating to minimize lens flare, ghosting, and color casts. The slim, lightweight aluminum frames prevent vignetting on wide-angle lenses and allow for easy stacking with other filters. Ideal for landscape, travel, and everyday photography, this kit supports the achievement of clearer, more vibrant images with reliable durability. The filters are housed in a protective case to ensure safe storage and transport while maintaining their optical performance over time. Measurements indicate a filter diameter of 55 mm and a thickness of about 4 mm per filter, with a total kit weight of approximately 85 g.
