NiSi 77mm True Color ND-VARIO Pro Nano 1-5 級可變減光鏡

I was worried about color shifts with variable ND filters, but this one keeps the blues and greens looking natural across the entire 1-5 stop range—the Nano coating also makes cleaning a breeze.

Switching from a screw-on polarizer to this variable ND was a game changer for run-and-gun video work, and I love that the Nano coating keeps smudges off even in dusty conditions. No color cast to speak of at the low end, which is exactly what I needed.

This variable ND filter lets me dial in exactly 1 to 5 stops of exposure without any weird color cast creeping in. The "true color" really holds up even when I crank it up for long-exposure waterfalls.
