Worlds Sharpest Protection Filter. 100% Guaranteed.

The X4UV achieves a higher optical resolution than any other protection filter, and thanks toour state-of-the-art and uniformly applied MRC16andnanotecnano coating layers, the X4UV lives up to the demands of the professional outdoor photographer.

The forefront of Nano Coatings built into both sides.

Our breakthroughnanotecNano 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, we 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 we 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 thoughit was quite a bit more expensive to manufacture, the feedback that we got from photographers was overwhelming –traction frames are better thanstandard flat black frames.

Full traction texture around the entire circumference of the X4makes it easier than ever to get off and on securely. Not only did we want to improve the design to make it easier and simply more practical, but we also wanted to take the materials to the next level. The X4is machined from brass, which is stronger than aluminum, binds and jams less on lenses and with other filters (or step-up rings) and it just provides a more reliablysolid feel.

Less becomes more.

The X4 UVfeatures anultra-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 X4UV’s double-threaded traction frame will accept all of your filters and existing lens caps.

We support you, and the world.

We stand behind every filter we make with our25 YearIroncladGuarantee.

Every X4 UV filterhas a unique serial number laser engraved onto the interior frame. When you activate your 25 Year Ironclad Guarantee, we 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 us to confirm non-genuine copies, and any feedback or insight you provide to us about your filter goes directly into future products.
