World's Sharpest ND Filter The X4 ND delivers the most color neutral performance and precise optical density thanks to years of research and advanced manufacturing methods. Featuring our spectrally flat coatings and a precision machined brass traction frame, the X4 ND is designed to be incredibly sharp and built to last a lifetime. World's Sharpest ND Filter The X4 ND delivers the most color neutral performance and precise optical density thanks to years of research and advanced manufacturing methods. Featuring our spectrally flat coatings and a precision machined brass traction frame, the X4 ND is designed to be incredibly sharp and built to last a lifetime. A design with traction. We engineer every one of our filters to withstand a lifetime of use in the field. That's why the X4 ND is precision machined from high-quality brass with our signature ultra-thin, double-threaded traction frame. The filter forms a weather-seal on the lens and is built to withstand extreme wind, salt water, dust, and any other abrasive elements found in nature. Our rugged design makes it easy to securely attach and remove the filter - even with gloves in cold conditions. Breakthrough Coatings Low light transmission and green flaring are common problems with uncoated glass. The Breakthrough X4 line of filters feature our state-of-the-art 16-layer Multi-Resistant Nano Coatings which combine to improve optical performance and durability. Eight layers of our proprietary MRC are evenly applied to both sides of the glass disk which reduces reflections and improves image quality and contrast by eliminating stray light. Additionally, our MRC16 layers protect the filter surface since the coating is structurally harder than the glass itself. Our breakthrough Nano Coatings are also applied to each side of the filter to further defend against the elements. The Nano Coatings repel dirt, water, and other debris by beading up on the surface rather than absorbing - making the filter easy and fast to clean. 25 YEAR SUPPORT We stand behind each filter with our 25 Year Support and US-based phone, email and live chat. NANO-COATING Each filter incorporates our state-of-the-art Nano Coating technology which repels dirt, water and other debris by beading up on the surface rather than absorbing and smearing. WEATHER-SEALED Our X4 ND filters are designed to hold up for years of regular use in the field. Each filter is weather-sealed and can withstand extreme wind, salt water, dust and other abrasive elements and conditions.
WORLDS SHARPEST AND MOST COLOR NEUTRAL ND From the moment you pick up X4 nd filter you’ll immediately feel the craftsmanship and quality. X4 77mm nd filter maintains a very well controlled and flat transmission all the way throughout the visible spectrum and into IR, delivering the worlds most color neutral results.
MRC16 OPTICAL COATING 16 Layer Multi-Resistance Coated to significantly reduce lens flare and ghosting while making the filter Anti-Scratch, Reduce Reflection, Water Repellent, Increase Surface Durability, Oil & Dust Resistant. All these fantastic attributes are essential for working effectively outdoors. Our proprietary MRC coating is structurally harder than the glass itself and the reduced reflections improve the efficiency since less light is lost.
NANOTEC In addition to state-of-the-art MRC, our optical engineers developed new nano coating layer technology, called Nanotec, from the ground up to repel dirt, water and other elements by beading rather than absorbing and smearing. Set in our workhorse and built to withstand extreme wind, salt water, dust and other abrasive conditions and elements.
FITMENT Our X4 10stop nd filter is compatible with all 77mm camera lenses. Your lens thread size will be printed underneath your lens cap or written somewhere on the lens barrel. Make sure you order the correct size otherwise it will not fit your lens.
25 YEARS SUPPORT This lens filter is guaranteed to be free from craftsmanship defects for 25 years. When you activate your 25 Year Ironclad Guarantee online we associate your X4 serial number to you, so any future discussions on this unique filter are tracked, issues recorded and all that stuff which goes into future product design.
