NiSi 127mm True Color Pro Nano CPL サーキュラーポラライジングフィルター

The knurled edge on the ring makes it easy to grip and adjust even with cold fingers, and I’ve noticed zero color shift in my shots. Cuts reflections on wet leaves beautifully without sacrificing sharpness.

I was skeptical about paying this much for a CPL, but the nano coating really does repel dust and smudges way better than my old one. The color stays perfectly neutral even when I'm rotating it to cut through reflections on wet leaves and glass.

Glare on wet rocks and leaves used to ruin half my waterfall shots, but this filter cuts it completely while keeping the greens true to what I actually saw. The nano coating makes wiping off spray effortless, and I didn't notice any color cast creeping in on my last golden-hour session.
