K&F CONCEPT 52mm Variable ND Filter ND2-ND32 1-5 Stops HD Optical Glass No Black Cross Waterproof Multi-Coated Adjustable Neutral Density Precise Light Reduction Smooth Rotation Nano-X Series FN712

HD Optical Glass Material: Variable ND filter: It's made of professional optical glass instead of optical resin, which can effectively reduce the surface reflection of the filter and greatly reduce the occurrence of glare. Rotate the filter to change the light intake without affecting the overall colour balance. No "X" cross on images: Say goodbye to the black "X" cross on images, K&F utilizes cutting-edge technology, and you'll say goodbye to this common problem with wide angle lenses and variable ND filters. Double-sided NANOTEC Coating: New nano coating technology, it balances the trajectory of light penetration well to ensure that the sharpness of the image is not compromised. It also makes the VND filter waterproof, scratch-resistant and anti-reflective, effectively preventing oil stains, fingerprints and scratches, and protecting precious lenses. Slim Frame: Ultra-slim edge design prevents wide-angle vignetting. The extra-tough aerospace aluminium frame ensures durability and anti-clogging. Choose the right size: This filter is compatible with all 77mm lenses. Please first check your camera's lens thread size (usually marked somewhere on the lens barrel or lens cap), a "Ø" symbol always precedes this number. i.e. Ø58 = 58mm lens thread size.
