K&F Concept 77 mm NANO-X Variable ND Camera Accessories

This K&F Concept 77 mm (77mm) variable neutral density filter is listed under Camera Accessories. Part of the NANO-X line, the ND2–ND32 filter reduces incoming light while preserving natural color balance. Its optical element is made from Completed Professional Optical Glasses rather than optical resin.

A NANOTEC green multilayer coating resists water, reflections and scratches and helps repel oil and fingerprints. The updated design minimizes the X-shaped artifact that some variable ND filters produce on wide-angle lenses. A slim aviation-aluminum frame reduces vignetting risk, resists wear and helps prevent jamming. Packaging may be the new or previous box version, selected at random.

Check your lens thread size before ordering; the marking may be on the lens barrel or beneath the cap, such as Ø58 for 58mm or Ø37 for 37mm. The package contains 1x NANO-X ND2-ND32 filter and 1x box. Package dimensions are 4.5 x 4.5 x 1.1 inches; weight is 3.52 ounces. The photo filter effect is neutral density.
