X1 Series Filters

Tracking Frame

4 MRC Layers

25 Year Warranty

We precisely machine each X1 filter from 3.5mm ultra-slim double-threaded traction frame from environmentally friendly aluminum

X1 features our state-of-the-art 4-layer multi-resistant coatings which help to eliminate flaring, ghosting and low contrast. 2 layers of MRC are applied to each side of the optical disk, resulting in a total of 4 layers (MRC8)

We stand behind each X2 filter to be free of defects in craftsmanship for 25 years, but they’ll easily last 50+ with proper care

Traction Design

The moment you pick up a Breakthrough X1 filter you’ll immediately feel the craftsmanship and quality. We precisely machine each X1 traction frame from environmentally friendly aluminium, and with it’s matte black finish reflections are absorbed rather than reflected into the lens barrel.

Prior to of our all-new line of X1, X2 and X4 traction designs, every filter borrowed the legacy flat black frame design, dating back to the 1940’s.

One of the problems with the flat black design is that it’s sometimes difficult to attach and remove the filters from the lens, frequently binding and getting stuck. By CNC machining texture into the X1’s aluminium frame it’s now easier than ever to get on and off, without getting stuck

Why 3.5mm?

In our lab tests 4.3mm was the frame width at which point vignetting becomes noticeable on 16mm wide-angle setups on full-frame setups. Any less than 3.0mm and lens caps don’t have enough surface area to grab onto. At 3.7mm vignetting is entirely eliminated.
