Breakthrough Photography X1 UV Filter 43mm

The X1 UV is our take on the legacy flat black UV filter with a modern spin: MRC4 and a 3.5mm ultra-slim weather-sealed frame.

The X1 UV Filter features 4-layers of our state-of-the-art and uniformly applied MRC, which means less flaring and ghosting than you’d normally see with uncoated protection filters.

Our modern coating chambers are airtight, producing a uniform coating visible to the human eye when holding the filter at a right angle to a direct light source.

Two layers of MRC are applied to each side of the optical disk, resulting in a total of 4 layers (MRC4). In addition to being structurally harder than the glass itself, our MRC coating process increases light transmission from 94.6% (without MRC) to 97.8%.

Glass without MRC coatings is highly susceptible to a range of optical phenomena such as flaring, ghosting (lower contrast as a result), and generally less saturation.
