Breakthrough Photography X4 UV Filter

While digital sensors don't react to UV light the same way film did, a UV filter is primarily used today as a protective layer for your lens. It shields your expensive front element from dust, moisture, scratches, and accidental bumps without degrading image quality.

Not at all. Because this filter uses premium Schott glass, it is designed to be optically neutral. You won't notice any loss in sharpness or unwanted color shifts in your images.

Brass is significantly more durable and resistant to jamming than aluminum. It provides a smoother threading experience when attaching or removing the filter from your lens, which is especially helpful if you frequently swap filters in the field.

The Nanotec coating is genuinely functional. It creates a surface that repels water and oil, making it much easier to wipe away fingerprints or raindrops compared to uncoated glass.

Yes, the filter features front threads that allow you to attach your standard lens cap directly to the front of the filter, just as you would to the lens itself.

The X4 is designed with a slim profile to minimize the risk of vignetting. However, if you are using an ultra-wide-angle lens, it is always best practice to test for any corner darkening at your widest focal length.
