K&F Concept Nano-X ソフトGND8フィルター (3段) ソフトグラデーションNDフィルター

I was worried about color cast with a 3-stop grad, but this one keeps the blues and greens looking natural in my landscape shots. The threads screw on smoothly and the glass feels solid, no vignetting on my 77mm lens.

Shot some seascapes at golden hour and the color cast is nearly invisible, which surprised me. The 3-stop transition is smooth enough that I don't notice a harsh line in the sky. Can't complain about the build quality either, it clicks into my holder firmly.

Finally got this to balance out a bright sky without making the foreground too dark. The 3-stop reduction was just right for keeping detail in both the clouds and the trees below.
