The Ulanzi UV01 explosion-proof UV filter 55 mm is a professional camera lens accessory for photographers who need reliable protection and optical performance. This 55 mm diameter UV filter features an explosion-proof construction with multiple layers of anti-reflective coating to minimize lens reflections and ghosting while providing protection against scratches, dust, and moisture. The filter effectively blocks ultraviolet light to reduce atmospheric haze and improve image clarity, especially in high-altitude or coastal environments. Made from high-quality optical glass and a durable aluminum alloy frame, the UV01 maintains consistent optical quality with minimal impact on light transmission or color balance. Its slim profile design prevents vignetting with wide-angle lenses, while the front thread accommodates standard lens caps and additional filters. This filter is compatible with all camera lenses with 55 mm filter threads and serves as a permanent protective layer for valuable camera lenses. The explosion-proof technology ensures that the glass remains within the frame if damaged, preventing glass shards from damaging the lens surface. Ideal for landscape, travel, and everyday photography where lens protection and optical performance are equally important. The standard color finish provides neutral performance under various lighting conditions without affecting white balance or color reproduction.
