NiSi 100x150mm Nano IR ハードグラデーションNDフィルター GND4 (0.6) 2段

The hard transition on this GND4 filter handles my sunrise landscapes perfectly, with zero color cast ruining the shot. The optical glass feels solid and the waterproof coating wiped clean easily after a splash of sea spray.

I was worried about color shifts, but this filter kept the sky’s natural tones perfectly. That 2-stop hard grad really made the rocky coastline pop against the clouds.

I’d been burned by cheap GNDs before, but this one really does stay true to color—no weird magenta tint in the highlights. The hard edge made the cliff-to-sky transition a breeze to balance, though I wish the case were a bit sturdier for the price.
