The Breakthrough Photography 77mm X4 UV Filter is a general use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter. To prevent internal ghosting and reflections while providing 99.4% light transmission, each glass surface includes eight layers of anti-reflection coating. This Multi-Resistant Coating (MRC) also offers greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. The Nano coating associated with X4 UV filters provides an additional ninth layer over the front MRC, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

This Breakthrough Photography UV filter is constructed from Schott B270 glass for increased optical clarity as well as color fidelity, and features a thin brass ring that is durable and features knurled sides for easy attachment and removal. It is also weather-sealed and useful as a general protective filter to leave on lenses at all times. Such filters help to reduce dust and moisture from reaching your front lens element and provide additional protection in case of drops or situations where scratching could occur.

    77mm X4 Brass UV Filter is rated 4.9 out of 5 by 17.
    Rated 5 out of 5 by from Works great on my Canon 5Ds R I shoot on the coast a lot and I recently noticed a loss in sharpness with my B+W UV filter when compared before/after shots on my new Canon 5Ds R. This company said the X3 UV was the sharpest, so I bought it to see if it was true knowing that I could return it if the claim was untrue, and actually I see sharper results on corner sharpness at 16mm when compared vs. my B+W. I tested the sharpness on my Canon 5D Mark III and didn't see a difference. I think this UV filter may be overkill if you have a lower resolution camera, but if you have a higher MP camera you'll see a discernable difference on corner sharpness if you shoot with UWA lenses. The brass ring on this one is great too.

    Rated 5 out of 5 by from Superb filter This filter is superbly coated and presents absolutely no flare or reflections, even with bright lights in the background. Colors are true and accurate and I couldn't be happier with this purchase.

    Rated 5 out of 5 by from Extremely impressed Build quality is exceptional. The outer ring is large enough that tightening the filter on isn't an issue. Only weird thing I noticed is that the filter seems to attract dust. Not sure if it's static in the air or what, but otherwise this is a 10/10.

    Rated 5 out of 5 by from Simply perfect Everything about this is first class. The knurling around the entire ring makes it easy to grasp and remove, and the threads are smooth. This is made using Shott glass and you can see the anti-reflective coating. The lens cap fits on it, and the reversible hood fits over it. For something that will be in the optical train it makes no sense to get less than the best, and this is as good as it gets.

    Rated 5 out of 5 by from beautifully made Breakthrough filters are far and away the best I have found. Their ND filters are exactly what they should be, and I have every expectation that the UV filter will be just as good. Have not used it yet, but from all appearances it should do a good job of protecting my front lens element while not degrading the image quality.
