How to Spot a Counterfeit B+W Lens Filter

Using a UV or Haze filter on your lens is a great step towards reducing glare, or even just protecting the expensive glass of the lens itself. You’ll feel a lot better about wiping water off a $75 lens filter than worrying about the $1000+ lens itself. Or in the case of ND or Variable ND Filters, you may find yourself needing these for long exposures or super bright situations.

But is it worth spending the money on a high-end filter? The short answer is yes, and there are a number of reasons why. Let’s look at those reasons and explore the rampant world of counterfeit lens filters that many people are receiving on from Amazon and how you can check to see if your B+W filter is genuine or not.

Negative Effects of a Cheap Filter

Vignetting

A poorly manufactured glass will cause vignetting on your images. While you may want this in some cases, it can be added in post so save it for the Instagram post and let your raw images be clean of this.

Light Flares or Glaring

Cheap glass provides poor optics, resulting in light flares or bouncing around before it actually hits your lens, causing bright pots or even unfocused/dirty looking areas.

Difficult to Clean/Keep Clean

A high-quality coating on the filter will help reduce smudges from your fingers, raindrops will slide off easier and when you do need to clean it with a cloth, it will come clean instead of causing smudges.

Discolouration

Along with those light flares and glares, you may also experience discolouration. This happens when the material of the glass has elements that don’t belong there, causing colours to show up that are not in your scene.

Hazy or Smudged Look

The image may look hazy or just like it’s a bit smudged like you took an oily finger and rubbed over the lens. Quality glass won’t do this.

Weight

Genuine B+W filters have a weight to them, you can feel them in your hand and you can usually immediately tell a fake when you pick it up, it will have no weight to it since it’s made of inferior materials.

Labelling, Typography & Location

Take note of the typeface on the images below, genuine B+W filters have the correct typeface, and it’s centred correctly on the side. Filter descriptions are printed on the front of the filter, not the sides.

Sound

Try tapping your fingernail against the glass, if it’s real you should get an audible glass sound like you were tapping your nail against a window in an old building. You can just tell it’s real glass. In the case of the counterfeit one I received, it sounded like I was tapping plastic.

Water Droplets

Water Droplet Effects on FiltersThe surface of the glass should have a coating on it that allows water to form nice little mountains, not spread out and lose cohesion. Drop a few droplets on your lens to see how it fares.

When you wipe them up, take note of how easily it comes clean too, a good lens with a proper coating will wipe easily and leave little to no streaks.

Buying a B+W Filter

Go to an authorized dealer, Adorama and B&H are both authorized and you can order online. Use the Schneider Optics (B+W) website to find a store near you.

A Worthy Alternative

If you have the cash to spend on the B+W filters I recommend them, they’re just so good you’ll never be disappointed that you got it. But if you’re looking for something a bit more manageable then check out GOBE. They’re an Australian company and they make decent stuff at a reasonable price. I have a 10-stop ND filter from them which I purchased on Amazon and it arrived fully legit. Works well and didn’t cost too much. They sell individual filters as well as filter kits starting with 2 filters in a particular size. In addition, you can grab lens adaptors for a wide range of camera setups.

Their Amazon Store is extensive so check them out – https://amzn.to/2Qd3FJP
