【Protective UV Filter】 This UV filter reduces the amount of ultraviolet light reaching the camera sensor. Perfect for eliminating the bluish cast on hazy days or when you’re shooting in mountains. More importantly, the filter protects your camera lens from dust, dirt, fingerprints, and scratches | 【Premium Optical Glass】 The premium optical glass features a 30-layer nano-coating to deliver improved image sharpness and added lens protection | 【Nano-Coatings】 Featuring 30 layers of optical coatings and a light transmittance of up to 99.8% (and a minimum light reflectance of less than 0.1%), the multi-coated UV filter cuts out ultraviolet rays ranging from 300nm to 410nm to reduce flare and ghosting while ensuring accurate color rendition. The coatings are also anti-static, oil-resistant, water-repellent, and scratch-resistant | 【Durable & Ultra-Slim Lens Frame】 Made of magnalium alloy, the filter frame is strong and durable. With precision manufacturing and a matte black anodized finish, the filter has less reflections from the metal filter frame. The 0.22”/5.5mm thick filter measures only 0.14”/3.5mm in depth when screwed on your lens to avoid vignetting when using wide-angle and telephoto lenses | 【Easy to Use】 Just screw the filter onto the front of your camera lens. Leave the filter on your lens at all times to prevent dust, sand, and grime from getting in. NOTE: Please find out your camera’s lens thread size before buying. The thread size will be marked on the lens with the ‘ø’ (diameter symbol) followed by a number.
