NiSi Explorer Collection 150×150mm Nano IR 減光フィルター ND64（1.8）6ストップ

I've been using this ND64 for long exposure seascapes and the glass really does feel more durable than my old filters—dropped it once on rocks with no scratches. The 6-stop density gives me exactly the shutter speeds I need for silky water effects even in bright midday sun.

Pulling this 6-stop ND filter out of the box, the glass felt noticeably more solid than my old one—no wobble or thin edges. Used it for a long exposure of a waterfall, and the neutral color cast was barely noticeable in the final shot. Perfect for getting those silky smooth water shots without worry

The glass really does feel tougher than other filters I've handled, which gave me confidence when screwing it on and off during a windy shoot. The 6-stop reduction was exactly what I needed to smooth out the water in my shot.
