K&F 46MM XV40 Nano-X Variable/Fader ND Filter, ND8~ND128, W/O Black Cross

K&F Concept 46mm XV40 Nano-X Variable ND Filter (ND8–ND128) – Professional fader ND filter with imported AGC optical glass, 31-layer Nano-X coating, ultra-slim anti-vignetting frame, and self-lock mechanism for smooth light control without the “X” cross effect.

The K&F Concept 46mm XV40 Nano-X Variable ND Filter (ND8–ND128) offers unmatched precision for photographers and filmmakers who demand control over exposure and motion blur. Made with imported Japanese AGC optical glass, this filter maintains the highest clarity and color neutrality, ensuring your images remain sharp and free from unwanted color cast.

Featuring an advanced self-locking frame, the XV40 eliminates the common “X” cross issue seen in other variable ND filters — even when using wide-angle or telephoto lenses. With a variable density range from ND8 to ND128 (3 to 7 stops), it allows seamless adjustment of light reduction for perfect exposure in bright conditions.

The Nano-X 31-layer coating provides superior protection, making the filter waterproof, scratch-resistant, anti-reflective, and oil-resistant. This ensures exceptional durability and optical performance in any shooting environment.

Its ultra-slim 7.4mm CNC-machined frame minimizes vignetting on wide-angle lenses (supports 31mm focal length without vignetting), while the non-slip grip design makes installation and removal easy and secure.
