B + W 49mm UV Protection Filter (010) for Camera Lens - Xtra Slim Mount (XS-PRO), MRC Nano, 16 Layers Multi-Resistant and Nano Coating, Photography Filter, 49 mm, Clear Protector

All you can say when you work with these B+W filters made by Schneider optical is that they are superb. Even the tactile feeling of the filter when you pick it up provides evidence that you are dealing with a superior product, kind of the like "the BMW of the the photography world" (which you can easily arrive at by replacing the "+" with a "W" in the name!). It's not to say there are not other excellent filters out there. There are. The Hoya brand, made primarily in Japan, also makes some truly impressive filters, both haze and circular polarizing, to name but two types, and I use these, as well due to their quality. But these B+W filters are just incredibly well made, and you can tell the minute you pick them up. They are made in Germany.This 43mm filter is a somewhat odd size that you'll need for Fuji's new 35mm f/2 prime lens and perhaps lenses from other brands. The filter itself is constructed using Schott glass, is very thin, and is mounted in an anodized matte black ring to reduce reflections. It's not a terribly expensive filter because of its small size, particularly in relationship to the cost of that lens you are putting it on! The screw threads are superbly cut, making a smooth on and off experience when changing the filter for a circular polarizer (and, as you have heard before, don't over-tighten the filter, or you'll be in rough shape trying to get it off: this applies to ALL filter brands and types). The filter presents itself with the slightest tinge of shading when you look through it, with light transmission measured at extremely high levels. The filter is designed to help with UV absorption which can theoretically remove the so-called "blue cast" result on some cameras.The nano-coating makes cleaning the filter, which you are always going to need to do periodically, much easier than on other filters. Also a nice touch, the square case with the embedded pad is really nice: I wish all filters came this way, or that these cases themselves could be purchased separately.If you read the information provided at the top of the Amazon page from the manufacturer itself, you’ll find all you need to know about this filter. As with the many other reviews you see posted here, I can easily say this is one of the best filters on the market, and if you are not adverse to the price differential, I would definitely go with this one first. If not, look at the high-end Hoya filters, but you might surprisingly find not much of a price difference, depending on the specific model. I can say it would be nice to have a complete set of B+W filters for all my lenses!

Background and Context: I've never given haze filters much thought in the past and have used many Hoya and Tiffen filters (obviously I'm not a professional) on my lenses for the sole purpose of protection (mostly because I have a toddler). I needed a filter for my Canon 24-105 F4/L, and Amazon recommended this filter in the "frequently bought together" section of the product description. I wasn't too sure about spending the extra money on a "magic coating" for a utilitarian haze filter, but all I can say is that I am amazed with this thing and that it is definitely worth the money (see math below for justification)!Problem Statement: I waste a lot of time cleaning my lenses/haze filters (you would too if you had a toddler)- and I still can't get them crystal clear. I also need a filter that won't distort my lens, and most of all, i need something to protect my lens from damage.Math and "Business Case": Assume you have to clean your lens once a week and it takes you 10 minutes each session (you are very thorough) on your uncoated filter. That's roughly 40 minutes a month which equates to 8 hours a year. If you paid someone at minimum wage ($8.25 if you lived in Illinois)to clean your lens, that would be ~$66.00 a year. Then let's assume you will spend 1 minute every two weeks wiping off your B+W filter- using the same calculations, your cost to clean that would be $3.30 a year. So your hypothetical potential labor savings would be about ~$62/year (assuming a non-unionized workforce)- or roughly the cost of the filter at today's amazon price. If you are looking to purchase this filter, most likely you make more than minimum wage; therefore if your time is money- this filter is definitely worth the time it gives you to do other things (such as take pictures or watching prime time network television).Evidence: The "aha moment" occurred when I took my camera to a water park for my son's birthday party; and as kids will do, they started splashing and shooting water guns at me. When I went to wipe off the lens, I was amazed that the water had actually beaded off and the filter remained relatively crystal clear- i didn't have to do anything. This never happens with my other filters as similar events would result in a long session with lens wipes/solutions, microfiber cloths, and a blower (and the filter still wouldn't be crystal clear).More Evidence: In addition, I am lazy with my cameras and the lens caps are rarely on. I just took a look at my camera and the filter is still crystal clear with no dust or smudges. I hate to sound like an infomercial but this is really amazing!OK, I've spent way too much time discussing a circular piece of glass.Bottom Line: If you hate spending a lot of time cleaning your lenses and you perceive your time as valuable, buy this filter!Cliff Notes:Pros: Crystal clear, solid quality (made in Germany like Sham Wows), and the coating really works. Will save you time.Cons: Pricier than other Haze Filters

Using on Fuji 27 2.8. Insanely nice lens. The filter had a mediocre review on some very technical review site so I was concerned but I couldn't find anything else from a known manufacturer. Feels and appears very substantial and satisfying. Subjectively I can't detect any decrease in quality and I have produced some of the most vividly sharp and bright images I've ever done in 35 years thanks to the incredible fuji optics. If i was the kind of person who would chew his arm off worrying if I was throwing away image quality, I'd buy the Fuji filter, but I couldn't find it and it was more expensive.

What else can be said about B+W filter.They are one of the best manufacturers of filters in the world. Standing at the same levels as some Japanese brands.It fits great, the thread never caused any issues and the image quality is not being affected as a result of the filter.

Tenía dudas respecto a la autenticidad del filtro por algunos comentarios que leí aquí, así que cuando llegó lo revisé de inmediato en la web del fabricante y para mi tranquilidad si es auténtico. Es un gran filtro, de calidad superior en cuanto a cristales y fabricación general. Ten en cuenta que en lentes Leica antiguos de 39 mm, las tapas a presión no se ajustarán bien.

O filtro é de excelente qualidade, totalmente translúcido, uso para proteção da lente e ele é bem nítido. A B+W é uma marca alemã de altíssima qualidade e muito preocupados em oferecer produtos perfeitos.

En mi pedido solicité un filtro XS-PRO UV de 58 mm. y me enviaron uno de 72 mm, me vi en la necesidad de hacer una devolución de forma inmediata , con las molestias y perdida de tiempo que esto ocasiona. Tendré que volver a solicitar la compra, espero que en esta nueva ocasión si me envien el filtro correcto (58 mm) pues he elegido esta marca por ser de muy buena calidad. Les doy una estrella por el servicio y las 5 estrellas por la calidad del producto.
