Es gibt günstigere Schutzfilter als der B+W 007 Clear XS-Pro Digital MRC Nano, aber keine so wertigen zu diesem Preis.Exakt verarbeitet, aus Vollmetall, stabil. Gerade der Nano ist so klein wie möglich. Dadurch trägt er nicht auf und Gegenlichtblenden sind problemlos zu montieren.In der Abbildungsleistung mit und ohne Filter (007 Clear) ist kein Unterschied feststellbar.Wenn der Filter nur ein mal das Objektiv oder das Objektivglas geschützt hat war er sein Geld mehr als Wert.Ich habe auf all meinen Objektiven vor der ersten Benutzung B+W Clear Filter montiert.

Comme toujours avec B+W, la qualité est au rendez-vous. Aucune incidence sur la luminosité, ni sur la qualité de l'image.

I’m a well known professional photographer and I “thought” an extremely savvy consumer, too. Lo and behold, through lots of research I have learned that most of the B+W and Hoya top of the line filters I have bought over the past 15 years are fake. Here’s what I’ve recently found to ensure getting legit ones here at Amazon:HOW TO SPOT A FAKE:Some fakes are easy to spot. The inner ring typography will be white instead of the gold color used by B+W in recent years. Now, the counterfeiters are beginning to make the inner type gold just like B+W. However: SEE PHOTO ABOVE. Note that the font of the fake at right is slightly thinner and just barely italic. Read on for more detail detective work tips below.AVOID THIRD PARTY SELLERSI truly believe in supporting small businesses but most of the B+W and Hoya filters out there from other resellers are indeed fakes. I trust in “Shipped and Sold from Amazon.com” yet some other third party reseller dealers are not genuine.BUY B+W ONLY WITH NEW AUTHENTICATION SYSTEM:In 2019, B+W fully switched to a new type of Hologram and authentication system. So if you are currently buying a new filter here, look for the red “Target” hologram logo on the side. Each box has a unique six digit number that you can check on the B+W website. After you enter the info, the website verifies if legit. Also, take a cellphone picture of the QR code on the box. If you are not automatically linked to the company website, it’s a fake.Earlier, I was fooled by counterfeits that simply had a scannable and seemingly legit 3D QR code. Did I bother to check. Nope! That was a mistake as when I just recently checked for the first time the link is to a non-existent website with the URL for sale!CHECK FOR REFLECTIONS ON THE FILTER ITSELF:Using the black-colored back of the B+W box, place the filter face down on it. Hover above. You should see almost no reflection of yourself, just very faint shadows. Cheap fakes are mostly like window glass with lots of reflections that weaken quality lenses bigtime. The glass for genuine filter will seem almost invisible.CHECK FILTER MARKINGS CAREFULLY:B+W and Hoya do change these over time so if you are seeing different typography styles and colors this does not mean they are fakes. For example, the current B+W logo on the side of the filter is sans serif type while older filters had the classic serif, bolder logo style.XS-PRO Nano CLEAR MARKINGS:As of 2021, for the XS-PRO Nano CLEAR series, all type will be a rich gold color. All gold type on the inside ring will be in CAPS except for lowercase “nano.” Thus, the markings are in the same style as the UV version.XS-PRO Nano MARKINGS:As of 2021, for the XS-PRO Nano series, all type will be a rich gold color. All gold type on the inside ring will be in CAPS except for lowercase “nano.”F-PRO MARKINGS:As of 2021, for the F-PRO series, all type will also be a rich gold color . All gold type on the inside ring will be in CAPS except for lowercase “Haze” for UV filters. The “x” in “1x” will also be in lowercase.WEIGHT:All of the series above are brass filters with impeccable machining. Brass filters weight more. Simply get a gram scale and weigh a filter “Shipped and Sold by Amazon” in comparison to a filter you suspect as fake. This, plus carefully checking reflections carefully helped me determine how to discern a real filter from a counterfeit.SPELLING MISTAKES:I found B+W fakes long after I’d bought them by carefully examining the box. Beyond fake QR codes, I found boxes with the word “licensed” mistakenly spelled as “licensed.”Hope this long review has been of some small help. I still can’t believe I was so thoroughly hoodwinked, literally for years. I also love some of the better Hoya filters but, unlike B+W, they do not seem to have a sophisticated counterfeit checking system yet in place.Keep shootin’ strong!

Buen filtro

Fine thread too. I have see for sometime for another review

Filtro ultra sottile di protezione in cristallo temperato nano-tec per lente frontale degli obiettivi fotografici. Un prodotto top di gamma di una delle principali aziende del settore. Dei diversi che ho acquistato per le ottiche di corredo ho apprezzato la fluidità della filettatura che non arriva mai al grippaggio nell'accoppiamento con gli obiettivi. Non ho rilevato un degrado apprezzabile dell'immagine con il suo utilizzo. Attenzione (in senso generale) al fatto che i filtri applicati all'interno di paraluce a baionetta sono più prominenti rispetto alla lente frontale delle otiche, con il rischio di non essere del tutto schermati da flares o raggi di luce; ridurre pertanto l'incidenza con la sorgente luminosa.

I have purchased six B + W XS-PRO filters of different kinds in the last 6 weeks using both Amazon Australia and Amazon US as well as a well-known New York-based photographic retailer. This is what I found to help identify 2 suspect filters received, both from US sources through Amazon. Other filters received from Amazon US and replacements from reputable dealers in the US had no issues!I can be very certain that the items sent to me were counterfeit based on the following observations of items in my possession and online research of the manufacturer's and retailers' websites.These comments pertain to additional orders for:(1) B+W 72mm XS-Pro HTC Kaesemann Circular Polarizer with Multi-Resistant Nano Coating, and(2) B+W 77mm XS-Pro Clear with Multi-Resistant Nano Coating (007M)- Weight differential says not brass but aluminium. Does not have the same "solidity" or "weightiness" as genuine article. If you have the equipment to measure small enough, weighing will confirm - both cases- White printed lettering rather than gold embossing or engraving on filter; slightly different font? - both cases- Hologram not consistent with regular B + W boxingin case (1) a poor imitation which just didn't function as a hologram. No proper reflective qualitiesin case (2), the "hologram" was the previously widely reported small green square type with the wording "Genuine Product" (LOL!). This hologram was of a categorically different kind and placed on the front rather than the side of the box- Boxed in old-style packaging no longer used by B + W; contemporary boxing does not have semi-circular see-through cut out any more - both cases; and not evident in any other box containing genuine itemsIn case (1) the box was sealed on top flap with clear plastic strip overwritten with details of filter. No other of the 6 W + B filters received came in sealed boxes. These new boxes have a gold sticker with black printing placed on front of box with filter details and manufacturer ID. Product details with barcode on the narrow face of box opposite the hologram- Both cases had barcoded sticker placed on front or side of box with dealer (Amazon?) part number and the word "NEW" printed underneath some basic filter info. NB: these "barcodes" do not have underlying numbering as with a genuine product barcode but rather only the Amazon/dealer part number printed distinct from the code in different font. Genuine products had no such stickers, ostensibly since product info and barcode sticker already placed on box by manufacturer as described above. Accordingly, these stickers seem only to identify dealer information (similar in both cases) and, by extension, counterfeit products- Clear plastic case containing the filter does not have "B + W FILTER" embossed on it as contemporary product does - both cases- In case (2), where a completely different filter was received, the order of placement of embossed information on the filter ring itself was reversed- And in this case, the wording "XS-Pro DIGITAL" appeared instead of "XS-PRO DIGITAL"- In case (2), the manufacturer's part number on box did not correlate with the product ordered. In this case, neither the advertised description as ordered nor the information on the box could be correlated with information printed on the actual filter itself. Wrong product in the wrong box and neither what I ordered! Obvious giveaways, to be sure, but worth mentioning as to the lengths these shysters will go to make the deception look real enough to vendors (who thereby remain 'innocent') to avoid scrutinyThe good news is that real B + W 'XS-PRO' filters are actually really good value, even at the price, and of such excellent quality and performance that these characteristics become even more obvious once you experience the real thing. The brass construction and fine-tolerance machining means that they glide on with a silky smooth action and you'll probably never have to use a filter wrench. The snug fit means you don't have to overtighten. Once replaced with genuine items, the polarizer produced dramatic effects on reflections from otherwise over-bright, over-exposed, shiny or wet surfaces, deepened wishy-washy blue skies, and sharpened cloud formation details.I now use B + W XS-PRO clear optical glass with nano coatings on all my lenses for protection only. Don't bother with UV filters of any kind if you have a high-end DSLR since the camera itself filters UV light. And that's another thing about fakes: they smudge so much more easily and it's far more difficult to remove smears and grease than with a genuine high-end B + W product with their 8 protective coatings. Comparatively, within the B + W range, the more expensive high-end filters with nano coatings show significant differences in both production and performance quality and their ability to resist smearing and scuffing such as to fully justify the price.Brass as opposed to aluminium allows for finer tolerances and is clearly superior overall. Moreover, once I had the real thing and experienced the high technical performance of the polarizers and neutral density filters, I couldn't contemplate anything less than the B + W top range any more. And if you're paying a couple of thousand or more for a lens, when it makes no difference to your image quality, it just becomes sensible to protect the front end of the lens in the event of bumps or more serious accident. A brass clear protector ring, as opposed to aluminium (aluminum), will not crush or distort as easily in a camera drop and so also supports the overall shape and structure of the front end of the lens and just might help avoid more serious damage.Happily, I've been able to claim and receive full refunds from both Amazon and third-party dealers and replace the fakes through Amazon itself and a reliable photographic shop in New York.Thanks to all those who've posted info about fakes and helped me to identify the counterfeits. The job would have been harder if not impossible without your information to alert me initially to what was going on. Hope this continues to help.The real deal B + W XS-PRO filters are 6 stars all day long!!
