• Material: Made of complete professional optical glass, not optical resin. Filters reduce light intake without affecting the overall color balance
• There is no "X" cross on the picture: Say goodbye to the "X" cross on the image, K&F adopts cutting-edge technology, and you will say goodbye to the common problems of wide-angle lens and variable ND filter
• Nanotechnology: Our optical engineers have developed a new nano coating technology, a green coating that is waterproof, scratch resistant and reflective, to effectively prevent oil stains, fingerprints, scratches and protect precious lenses
• Professional design: ultra-thin edge design to prevent wide angle fading. Super sturdy aviation aluminum frame, ensuring durability and preventing seizure

Note: Please verify the lens thread size of your camera before ordering (usually marked somewhere on the lens barrel or printed under the lens cover).
