Breakthrough Photography X4 UV Filter

Brass is significantly more durable and less prone to binding or jamming when attached to your lens. Because it is a harder metal, it resists cross-threading and holds up better to the wear and tear of frequent mounting and removal.

No. The X4 uses high-quality SCHOTT Superwhite B270 optical glass, which is designed to be completely neutral. You should not notice any loss in sharpness or color shifts, even when shooting with high-resolution sensors.

The Advanced nanotec® coatings are highly effective at minimizing internal reflections and ghosting, especially when shooting in high-contrast lighting situations. It also makes the glass surface easier to clean by repelling water, oil, and dust.

Yes, the X4 features front threads that allow you to stack additional filters. However, keep in mind that stacking multiple filters can sometimes introduce vignetting, especially if you are using a wide-angle lens.

While the filter itself is not a weather-sealing device for your camera, the brass frame and high-quality glass construction provide a robust barrier against dust and moisture for your front lens element. It is an excellent choice for protecting your optics in challenging environments.
