X1 UV Filter for Camera Lenses - Weather-Sealed UV Filter with Protection Against Dust and Water - MRC4, Ultra-Slim, 25 Year Support, by Breakthrough Photography, 55mm

I'm still on the fence about using UV filters overall and will be conducting some testing with and without UV filters in general.That said. If you decide in favor of having a UV filter on any of your lenses...this is the one! Breakthrough certainly has some higher-end UV filters and based on what I've read, they are excellent and likely worth the money. In my opinion, however, the X1 series seems to be the best price/performance balance.The build quality is excellent. It's real glass and real metal! I did find it a little challenging to screw the filter onto my lens at first. That, however, is a result of how very thin and unobtrusive the filter is, not because of the threading.I did some very quick, low quality, jpg shots to give me a sense of any color issues. I used a simple daylight white balance setting on my camera and took a couple of images both with and without the filter. I could not detect and obvious color cast, nor any obvious image degradation.I will conduct some extensive testing with high quality 24Mpix RAW images under controlled lighting with custom properly set white balance and will update this review with that data when complete.

I was really excited about this product when I ordered it. "Made in USA" with a 25-year warranty. It arrived in a nice box similar to Apple iPhone. Unfortunately the performance is disappointing. Whenever I buy this type of filter I do a simple test, shooting against a strong light source and looking for flares/reflections. I ended up having to buy another filter from a brand I was already familiar with (B+W XS-Pro). The B+W XS-Pro costs 2x as much but performs 10x better. I attached 3 photos to this review... Left: taken with this product (X1), Right: taken with B+W XS-Pro, Middle: Taken with no filter.

Having purchased a pair of Canon's Great Whites (an EF 100~400mm f/4.5~5.6L IS II and an EF 70~210 f/2.8L IS II), those lens's seemingly enormous 77mm front elements seemed to call for the best quality protection available. Breakthrough Photography's assertion that their 77mm UV MRC4 "Ultra-slim" filters are "Weather-sealed," combined with their willingness to undertake a 25 year commitment to support of these registered serial-numbered filters sealed the deal, so-to-speak. The filters appear to have been precisely manufactured and show no apparent flaws. Only time and use will test the claims. I have every hope that use of these filters will validate Breakthrough Photography's unambiguous claim of quality.

I recently ordered three different Breakthrough Photography UV filters. The first two arrived shrink wrapped, and the exterior box and interior filter case both had seals. The third filter I ordered from was not shrink wrapped, did not have a seal on the exterior box, and the interior case had a seal but it was popped open. Clearly Amazon sent me a returned item. I contacted Breakthrough Photography and they immediately sent me a replacement filter with a label so I can returned the used filter.The filter itself looks very well made and is considerably less expensive than a UV filter from B+W, so needless to say I am a pleased customer. Five stars for outstanding customer service by Breakthrough Photography.

I've had a lot of different kinds of filters (UV, Polarizers, ND) in various sizes for various lenses. When I came across this one, I decided that, though a bit pricey, I wanted to give this U.S. company a try. I'm happy I did. This filter seems very well made frame wise, the filter itself is crystal clear and cleans easily and the fit it perfect (and the packaging is the nicest I've seen on a filter). I live in the high desert area of New Mexico and, though I don't think you always need a filter on for protection, I do it here. When shooting outside, without notice, you can find yourself hiking through some pretty good wind with sand and dust. So I do it for protection mainly but, with this filter, I really don't think there is any negative effect on image quality.I'll use this one with confidence and, when I need anymore for future lenses or applications, I look at what Breakthrough has first.

I'm not sure about the negative review from 2016 but this filter is as good as you will find anywhere and at any price. Packaging oozes quality and the filter is superb quality - take it from a self-confessed pixel-peeper!!

well made , good quality and thin . Great value too

Excellent quality , well made and thin

I've only had this for a couple of weeks but as soon as I opened the box I realised that it was a very high spec. I have a high quality lens, Carl Zeiss ,on my camera so therefore wanted a high quality filter. so far it has been brilliant.

Little bit expencive but perfect.
