【UV FILTER PROTECTOR】 This UV filter reduces haze and minimizes ultraviolet (UV) rays while improving contrast. Perfect for capturing high altitude and snow shots without the blue dominant. Keep this filter on your lens to protect it from dust, scratches and bumps. 【High quality optical glass】 Quality optical glass protects your lens from dirt, scratches, fingerprints and unexpected damage. 【Nano-layers】 Featuring 30 layers of optical coatings and up to 99.8% light transmission (and minimum light reflectance less than 0.1%), the multi-layer UV filter blocks ultraviolet rays ranging from 300nm to 410nm to reduce glare and ghosting while ensuring accurate color rendering. The coatings are also anti-static, oil-proof, water and scratch resistant. 【Powerful Lens Frame】 Made of aluminum and magnesium alloy, the filter frame is strong and durable. With precision fabrication and matte black anodized finish, the screw-on filter has less glare due to the filter's metal frame. The 5.5mm thick filter is only 3.5mm deep when screwed onto your lens, avoiding lens vignetting - ideal for wide-angle and telephoto lenses. 【Compatibility】Compatible with all 72mm lenses. Please inquire about the thread size of your camera lens before purchasing. The thread size will be marked on the lens or lens cap with the 'ø' followed by a number.
