Capture Critically Sharp Images.
In addition to having great optical performance, X1 UV Filter features our state-of-the-art multi-resistant coating. Two layers of MRC are applied to each side of the optical disk, resulting in a total of MRC-4.

In addition to being structurally harder than glass itself, our MRC coating increases light transmittance and prevents common flaring, ghosting, low-contrast and all the rest. We dont recommend uncoated filters as glass without MRC coatings are highly susceptible to a range of optical phenomenon such as flaring, ghosting (lower contrast as a result) and generally less saturation.

Thin and light. Yet rock solid.
The X1 features a 3.5mm ultra-slim double-threaded frame profile to eliminate vignetting on wide-angle full-frame setups. Why 3.5mm? In our tests 4mm was the frame width at which point vignetting became noticeable on 16mm wide-angle setups on full-frame cameras.
