NiSi 100x150mm Nano IR ソフトグラデーションNDフィルター ND8（0.9）3ストップ

Finally a soft grad that doesn't add that ugly blue tint I've seen with others. The optical glass keeps everything sharp even when stacking with a polarizer. Very happy with how natural the colors look on my coastal landscape shots.

Finally got a shot where the sky was two stops brighter than the foreground and this ND8 balanced it perfectly—no weird color shift like I've seen with cheaper glass. The hard edge on the gradation really helps when mountains jut into the horizon.

I was a bit skeptical about "no color cast" claims, but this ND filter truly delivers—the colors in my landscape shots are exactly as I saw them. The high-definition optical glass makes a noticeable difference in sharpness when balancing a bright sky with darker foreground elements.
