NiSi SQUARE EXPLORER 100X150MM SOFT IR GND8 3 STEG

NiSi SQUARE EXPLORER 100x150mm Soft IR GND8 – 3 Stops, B270 Tempered Glass

This NiSi Explorer graduated neutral density filter (GND8 / 0.9) is a 100x150mm soft-transition filter that reduces light by 3 stops. It uses extra durable B270 tempered glass, includes IR coating and NiSi’s Nano coating, and is made for active photographers and outdoor adventures.

Key features

• 100x150mm graduated neutral density filter in the NiSi Explorer series.
• GND8 (0.9) density, which reduces the light by 3 stops.
• Soft transition between the dark and clear areas, suitable for horizons with trees, buildings or mountains.
• Upper half of the filter is dark gray and reduces light; the lower half is clear.
• B270 tempered glass that has been hardened to increase durability.
• IR coating to reduce infrared contamination.
• Nano coating that repels dirt, water and oil, matching NiSi’s regular filter coatings.

How this GND8 helps your photography

Use this soft graduated filter to balance bright skies with darker landscapes. The three-stop reduction in the upper half evens out differences in brightness, increases color saturation and makes clouds more visible. Because the transition is soft, the filter works well when the horizon is interrupted by trees, buildings or mountain ridges.

Compatibility and system use

The NiSi 100mm Explorer filters are compatible with the NiSi 100mm filter system. You can use them on lenses equipped with a filter thread from 49 mm to 95 mm when combined with the appropriate holders and adapters for the 100mm system.

Durability and care

NiSi Explorer filters undergo a tempering and hardening process to make them much less prone to accidental damage; the B270 tempered glass is described as twice as durable as other typical glass filters. However, the hardening does not make the filter unbreakable, and the protective effect may decline over time. The Nano coating helps repel dirt, water and oil, which simplifies cleaning and maintenance.
