Our all-new and internally developed CPL film is at the core of the X4 CPL, and we manufacture it right here in California. To achieve the worlds most colour neutral performance, we had to develop a unique approach to manufacturing rather than selecting off-the-shelf CPL film common among filter manufacturers, which is designed and intended for LCD panels, not photographic optics.

16 MRC Layer

Increases light transmission to 99.4% and creates a protective layer that's structurally harder than the glass

Nano Coating Layers

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

3.1mm SCHOTT B270

SCHOTT Ultrawhite B270 optical glass made in Germany

Tracking Frame

Full traction texture around the entire circumference of the X4 makes it easier than ever to get off and on securely


Built to withstand extreme wind, salt water, dust and other abrasive conditions and elements

25 Year Warranty

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
