Irix Edge 100 SR Hard Gradual GND8 0.9 Filter 100x150mm

Built on Irix's toughened SR glass, this Edge 100 Hard Gradual ND8 drops a bright sky 3 stops across a sharp transition line — ideal over ocean horizons where a soft gradient would bleed into the water.

The tinted zone applies 0.9 optical density (3 stops) with an abrupt transition for flat, even horizons. SR-series glass adds high scratch resistance, resilience to mechanical damage and internal compression stress, and a dirt-repellent nano coating — with the coatings covered by a 5-year warranty. A filter case is included.
