Designed to protect your camera lens, the Marumi EXUS uv l390 is a clear, transparent filter with surface reflection of less than 0.3% that does not affect the visible light range. In addition to its excellent low-reflection characteristics, the filter features a new antistatic coating that protects the lens from static clinging of dust and dirt, while allowing easy cleaning of water spots and fingerprints. The EXUS Lens Protect glass is flatter and stronger than conventional filters. Designed to protect a camera’s expensive lens system from scratches and impact, EXUS L390 is essential gear for both digital and film photographers.
