Product Details

Our cutting edge research and alternative manufacturing methods deliver the most color neutral ND filter for the discerning landscape photographer. In the time that it took us to achieve the X4 ND’s unparalleled color neutrality we also took our hand at redesigning the filter frame from the ground up.

 

Sharpness

Worlds Sharpest ND Filter. 100% Guaranteed.

The X4 ND features SCHOTT Superwhite B270® optical glass, which is an ultra clear crown glass. It is produced by melting high purity raw materials and then made using the continuous draw process. The result is excellent transmission in the ultraviolet, visible, and infrared spectrums, and a high surface quality that accepts our state-of-the-art MRC and nanotec® coatings exceptionally well.

 

Lee Big Stopper vs. X4 ND

 

MRC16


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 color.



WEATHER-SEALED

We specifically designed the X4 ND as a workhorse ND filter for field work, built to withstand extreme wind, salt water, dust and other abrasive conditions and elements.

NANO COATINGS

The X4 ND incorporates our state-of-the-art nanotec® Nano Coatings Technology, which beads water and other elements rather than absorbing and smearing.

25 YEAR SUPPORT

We stand behind each X4 ND filter with our 25 Year Ironclad Guarantee with US-based phone, email and live chat support.



 

How does poor quality MRC affect image quality?


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.
