NiSi 150x170mm Nano IR Medium Graduated Neutral Density Filter - ND4 (0.6) - 2 Stop

The NiSi 150x170mm Nano IR Medium Graduated Neutral Density Filter is a rectangular filter designed specifically for landscape photography, helping photographers balance exposure by darkening bright skies whilst maintaining natural exposure in other regions of the image. Crafted from premium optical glass with high-definition nano coating on both sides, this filter delivers true-to-life colour without cast and protects against unwanted infrared light that can appear as a red colour shift when shooting at small apertures. The medium-edged transition zone is 40% smaller than soft GND filters, making it ideal for sunrise and sunset photography where buildings, mountains and other elements protrude into the skyline.

• Medium-edged graduated density for precise exposure control in landscape images
• Infrared protection coating eliminates red colour cast at small apertures
• Premium optical glass with water and oil-repellent nano coating for durability
• Compatible with the NiSi 150mm S5 filter system for lenses without standard filter threads
• 2-stop reduction (ND4, 0.6 density) provides controlled light reduction
