Home / Breakthrough Photography X4 6-stop Neutral Density Filter
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.
Lee Big Stopper vs. X4 ND
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.
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.
The X4 ND incorporates our state-of-the-art nanotec® Nano Coatings Technology, which beads water and other elements rather than absorbing and smearing.
We stand behind each X4 ND filter with our 25 Year Ironclad Guarantee with US-based phone, email and live chat support.
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.
