Breakthrough X4 UV Filter

Breakthrough Photography is a filter research and manufacturing company that designs, manufactures and sells the worlds sharpest and most colour neutral ND, UV and CPL filters. Breakthrough X4 UV Filter is the third step in their range.

Worlds Sharpest Protection Filter.110% Guaranteed.

The X4 UV achieves a higher optical resolution than any other protection filter, and thanks to their state-of-the-art and uniformly applied MRC16 and nanotec nano coating layers, the X4 UV lives up to the demands of the professional outdoor photographer.

Critically Sharp SCHOTT B270

The X4 features SCHOTT Ultrawhite B270 optical glass made in Germany. Breakthrough Photography’s state-of-the-art multi-resistant coating has 16-layers (MRC16) which increases light transmission to 99.4% and creates a protective layer that’s structurally harder than the glass.


The forefront of Nano Coatings built into both sides.

Their 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.

A breakthrough design that has traction.

In addition to featuring the highest resolving optics for today’s highest quality lenses, Breakthrough Photography wanted to create a filter that was thinner and therefore lighter, but at the same time increase its functionality and it’s durability. That led to some really surprising design challenges and innovations.

To achieve this they took the entire filter concept and went back to the drawing board. It’s incredibly important to have filters on tight and very secure, as camera equipment unfortunately gets banged around quite a bit, and a filter falling off is not a good situation to be in.

Even despite the early tooling challenges during the prototype phase, and even though it was quite a bit more expensive to manufacture, the feedback that they received from photographers was overwhelming – traction frames are better than standard flat black frames.

Full traction texture around the entire circumference of the X4 makes it easier than ever to get off and on securely. Not only did they want to improve the design to make it easier and simply more practical, but they also wanted to take the materials to the next level. The X4 is machined from brass, which is stronger than aluminium, binds and jams less on lenses and with other filters (or step-up rings) and it just provides a more reliably solid feel.

Less becomes more.

The Breakthrough X4 UV features an ultra-slim double-threaded 3.1mm Traction Frame which eliminates vignetting and light falloff on full-frame wide-angle setups while still working with all your lens caps.

The X4 UV’s double-threaded traction frame will accept all of your filters and existing lens caps.

Breakthrough Photography support you, and the world.

Breakthrough Photography stand behind every filter they make with their 25 Year Ironclad Guarantee. For every sale they also give 5% directly to non-profits, helping make the world better. Great support all around.

Every X4 UV filter has a unique serial number laser engraved onto the interior frame. When you activate your 25 Year Ironclad Guarantee, they assign this serial number to you.

And after activation, and in the event you ever need to contact us for support, you don’t need your purchase information or receipt ever again. This also allows for them to confirm non-genuine copies, and any feedback or insight you provide to us about your filter goes directly into future products.
