All optics can use an extra measure of protection from scratches, bumps and dings. Small price to pay for this type of lens protector. Highly recommend for cameras, rifle scopes and other expensive optics.

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 many of the B+W and Hoya filters out there from other resellers are indeed fakes. I trust in “Shipped and Sold by 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.F-PRO CLEAR MARKINGS:As of 2021, for the F-PRO series, all type will be a rich gold color . All gold type on the inside ring will be in CAPS including the word NEUTRAL.XS-PRO Nano MARKINGS:As of 2021, for the XS-PRO Nano series, all type will also 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.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.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 Hoya and B+W fakes long after I’d bought them by carefully examining the box. For example, 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!

Un filtro de gran calidad, adecuado para proteger objetivos de gran calidad. Los hay más baratos, pero no creo que se comparen.

He tenido toda clase de filtros, Hoya y sobretodo Filtros Nikon, eran mis preferencias. Compré este filtro y quedé impresionado por su calidad y acabado, parece muy robusto, mejor que todo lo visto hasta la fecha, en la medida 86 mm., pesó 60 gramos en la báscula, se nota la buena calidad y terminación del marco de latón, que no se altera por los cambios de temperatura, lo que redunda en un roscado y desenroscado fácil; el cristal óptico claro alemán que usa este filtro es el de mejor calidad, el mismo que usan los filtros zeiss, el ensamblado es perfecto, en resumen muy recomendable. Comprar filtros en Amazon o en sitios con garantía, que aunque pueden ser más caros, son productos genuinos, no falsificaciones que circulan por la red "Made in China"

In an effort to help those trying to decide whether these filters are really worth the money, the following is a list of my own impressions and conclusions:PROS:+ Employs Schott glass (made by Schneider Krauznach), which is manufactured to a very high optical standard+ The filter benefits from an effective seven-layer MRC (Multi-Resistant Coating) - which is water and dirt repellant, and is reputed to be as hard as the glass it adheres to+ Uses tougher brass mounting rings, which are less likely to distort or wear than aluminium equivalents+ Does nothing but protect the lens without impairing overall image quality (modern digital cameras do not require additional UV filtration)CONS:- Using brass in the construction makes these filters noticeably heavier than their traditional (aluminium) counterparts- The front bezel is quite deep, so vignetting may become an issue when using very wide-angle lenses (wider than 24mm on a full-frame camera, or 18mm on an APS-C camera.) If you imagine this might be a problem, buy the instead - which is usable on lenses as wide as 17mm (full-frame) and 10mm (APS-C)- In this fitting, the filter is more expensive than the obvious rivals...but most probably better- There are counterfeits in the marketplace, so try and purchase from a reputable sourceIn conclusion:Buy these, and you can be sure that you're getting high quality filters for your high quality lenses. Highly recommended!

Its a permanent fixture on my D5200. Don't even notice it. Has already saved the main lens a couple of times from potential scratches - must have!

I chose a straight glass "filter" over the UV haze etc type of thingies. I really didn't want anything to get between a great lens and my target. I do believe that this filter is a great way to protect a valuable lens. To that extent I really like this product. But I'm giving it 4 rather than 5 stars because I found that cleaning the filter to be less than optimal. Thus, if you use a lens cleaning solution (like from Zeiss and such like) it leaves behind streaks. You have really rub the filter surface to get rid of those. And I have an issue with having to do that at all. Ideally, the solution will be applied gently with a soft microfiber cloth and the solution would evaporate without leaving behind any residue whatsoever. I did not find that to be the case. Hence, my disappointment. I have come to realize that the best approach is not to get the filter greased up or dirty at all to begin with and use only a Giotto rocket blower to get rid of any dust motes.

I have purchased many so call multi coated clear lens that out of the box were foggy & scratched when held up to any light source and looked through. This lens however is crystal clear out of the box holding up to view through via a light source.This is actually a neutral lens therefore it does not effect the images you take at all. The basic and primary function is one step out of many to protect your camera lens. It would be much less expensive to replace the B&W Lens than it would be to replace the camera lens if it were to get scratched, cracked, so on and so forth. You could leave this lens on at all times as its threaded on both ends so you can add additional lenses or other attachments without any problems all while protecting your camera lens. I personally switch between this clear lens and the B&W UV lens (010).I use this on my Canon SX40 HS so I do of course have to use an adapter purchased from Goja, which I have written several reviews on, in order to attach it to the front of my camera.I highly recommend this lens.

Thankfully, I have yet to test out this filter's ability to withstand damage/protect my extremely expensive lens. But I can speak to it's clarity and high build quality. I've used this on my Canon 24-105mm f/4 lens for several shoots and literally can't tell the difference between shots when this lens if off, and when it's on. I've studied side by side comparisons in detail in a variety of lighting conditions and can't tell any major difference between shots with this on and off my lens. So A+ on clarity.This also fits very well on my lens. Tight and like it was simply another part of my lens instead of being a separate piece. It also accommodates a large lens hood being placed on top of it with no problem. All the threads line up and fit perfectly. Hopefully I'll never have to discover if this can prevent my glass from cracking in event of a fall--but it's completely worth it in protect my glass from dust and scratches. When you are paying over a thousand for a lens, it's stupid not to make sure it's properly shielded. I've tried knockoff cheapo filters, and none have come close in terms of clarity and build quality. Highly recommend.
