K&F CONCEPT VARIABLE ND2-400 NANO-X 82MM FILTER

Unlock your creative potential with the K&F Concept Nano‑X Variable ND Filter (1–9 stops)—a versatile, high-quality light-control solution designed for both photographers and videographers. Built with precision Japanese AGC optical glass and protected by 28-layer Nano‑X multi-coatings, this filter minimizes glare, resist scratches, repels water, and maintains ultra-sharp clarity—even for 8K-resolution capture. The sleek 7.3 mm aluminum frame includes an ergonomic orange “putter” lever and clearly marked stop indicators, enabling you to effortlessly dial in anywhere from 1 to 9 f-stops for slower shutter speeds, motion blur, or cinematic depth of field. Despite its extensive range, the compact design reduces vignetting down to 16 mm full-frame, making it ideal for landscapes, waterfalls, or controlling exposure in bright daylight. Included in a rugged Nano-X pouch with magnetic lid, this filter is your all-in-one ND tool—powerful, portable, and ready for any shooting scenario.
