K&F Concept Nano-X ND8~128 Variabler Fader 72mm Filter

Took this on a sunny beach shoot and the nano coating handled salt spray and sand better than any filter I've used before. The variable range from 8 to 128 stops is perfect for getting smooth motion blur on moving water without switching filters. Really happy with how natural the colors stayed even

I was skeptical about variable ND filters, but this one surprised me—the nano coating really does repel water and dust, and the color balance stays neutral even at the darkest setting. It’s been great for long exposure shots on a bright day without any weird tint.

Finally, an ND filter that actually stays waterproof even in light rain—no more fogging up mid-shot. The glass is crisp enough that I don't see any color cast, which makes a huge difference for landscape video work.
