NiSi S6 PRO Circular IR ND32000 (4.5) 15 Stop for S6 150mm Holder

The NiSi S6 PRO Circular IR ND32000 is a professional-grade neutral density filter designed specifically for the NiSi S6 150mm filter holder system. This 15-stop filter reduces light entering the lens by 32000x, enabling extreme long exposure photography in bright daylight conditions. Featuring a 4.5 density rating, the ND32000 allows you to use wider apertures or significantly slower shutter speeds to capture motion effects like silky water and cloud movement. Constructed from premium optical glass with NiSi's proprietary Pro Nano Coating, it resists water, dust and scratches while maintaining optical clarity. An integrated infrared protection coating eliminates unwanted red colour casts that can occur when shooting at small apertures, delivering true-to-life colours in every shot.
