NiSi SWIFT 55mm True Color ND-VARIO Pro Nano 1-5級可變ND

I've been swapping between fixed NDs for years, and the smooth, stepless control from 1 to 5 stops is a total game-changer for quick exposure adjustments. Even at the darker end, the image stays clean and color-neutral, which I honestly didn't expect from a variable filter.

Finally, a variable ND that doesn’t cast a weird color cast—the "True Color" claim actually holds up in my test shots. I’ve been using it for outdoor portraits and the 1-5 stop range gives me just enough flexibility to nail the exposure without fumbling with multiple filters. The ring turns smoothly

The variable range is genuinely useful for quick exposure tweaks, and the nano coating did keep dust off during a dusty beach shoot. Only slight gripe is the ring feels a bit stiff when turning at first, but it's smooth enough once you get going.
