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.

Transmission spectrum using scan speed of 1200 nm/min at 2.00nm resolution.

Performance across the spectrum.

The color cast seen in most neutral density filters on the market can be seen on a spectral graph as deviations from a flat curve - usually a blue cast that results in an increase in % transmission from 400 - 500nm. The X4 ND has the flattest transmission curve throughout the visible range and well into infrared, leading to a more color neutral performance.

And thanks to years of research and development, the X4 ND is incredibly precise to the ideal optical densities. An optimal 10-Stop (3.0) ND filter has a light transmission of 0.1%. With an average light transmission of 0.108% across the visible spectrum, the X4 ND hits the mark with great accuracy giving you a more dependable baseline to set up shots.

X4 Design Drawing

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. And our rugged design makes it easy to securely attach and remove the filter - even with gloves in cold conditions.

X4 Filter Design

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 Coating (MRC16) and our nanotec© 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 nanotec© Nano Coatings are also applied to each side of filter to further defend against the elements. The nanotec© coatings repel dirt, water and other debris by beading up on the surface rather than absorbing - making the filter easy and fast to clean.

WHAT THE PROFESSIONALS SAY

"The X4 ND is the sharpest and most color neutral ND I've ever used."

“It is a truly rare happening when I run across a product and can’t seem to find anything negative to add in the review. In the course of bringing you an unbiased and honest commentary I usually find some minute problem which I feel is worth sharing. 

I can earnestly and confidently say that I have found the X4 ND filter from Breakthrough Photography to be nothing short of exceptional.”

"There is absolutely nothing bad to say about the quality of this filter; it is really exceptional. The SCHOTT© B270 glass is wonderful, and the brass metal construction gives a great, high quality feel to the unit.

I have never used a higher quality or better built filter"

“Breakthrough sent me an evaluation filter along with some very strong claims including: “The X4 ND is the world’s sharpest and most color neutral ND filter.” Well, that is exactly what I’m looking for, so I was persuaded to spend the time testing the X4 head-to-head against my previous favorite, the Singh-Ray Mor-Slo. Turns out they were right.”
