World's Sharpest GND. 100% Guaranteed
16 MRC Layers
Nano Coating Layers
25 Year Warranty
Increases light transmission to 99.4% and creates a protective layer that's structurally harder than the glass
Our breakthrough nanotec® Nano Coating layer repels dirt, water and other elements by beading rather than absorbing, making it easier (and faster) than ever to clean
We stand behind each X4 ND to be free of defects in craftsmanship for 25 years, but they’ll easily last 50+ with proper care
World's Sharpest GND. 100% Guaranteed
The X4 GND is the world's first GND to use tempered glass, the result is the most durable GND on the market. By using SCHOTT B270 optical glass, the X4 GND resolves critically sharp.
What's A GND
Graduated Neutral Density (GND) filter, is a rectangular filter that increases the dynamic range of your camera.
Shooting a sunset with a GND filter transforms a photograph from having blown out highlights to one with incredible dynamic range, and it does this in-camera, without the need for Photoshop, stacking multiple frames or HDR.
Critically Sharp SCHOTT B270
The X4 GND features SCHOTT Ultrawhite B270 optical glass made in Germany. The X4 GND is the world's first GND to use tempered glass, the result is the most durable GND on the market. Our state-of-the-art multi-resistant coating has 16-layers (MRC16) which increases light transmission to 99.4% and creates a protective layer that's structurally harder than the glass.
The MRC16 Effect
Our state-of-the-art multi-resistant coating (MRC) is an optical coating applied to both surfaces of the glass disk to reduce reflection and to increase surface durability. Our proprietary MRC coating is structurally harder than the glass itself and the reduced reflections improve the efficiency since less light is lost. The reduction of reflections also improves the contrast of the image by elimination of stray light. The real world result? Better contrast and colour.
Low light transmission and green flaring are common problems with uncoated glass. As MRC coatings are added to each side of the optical disk light transmission steadily increases with flaring steadily decreasing. In our lab tests light transmission apexes at about 16-layers of MRC, and slowly decreasing in transmission at 18 and above. 8-layers of MRC are applied evenly to both sides of each optical disk resulting in MRC16.
