Everything is very cut and dry here. This black diffusion filter works as intended, and it safely, securely gets the job done.
K&F Concept does a great job with making quality lenses at a pocket friendly price, so - as expected - this hits all the high points.

The filter is well made and durable. Images are crystal clear, and the desired effect is achieved at half the price of bigger name filters.

It attaches securely to my camera. The multi coating means the filter is scratch resistant.

Top quality at a great price here.

Always struggled with that harsh digital look that makes everything appear too clinical and sterile, so when I heard about black diffusion filters I decided to try this K&F Concept one. The difference it makes is honestly incredible and has become an essential part of my setup.

The 1/4 strength creates this beautiful soft glow around lights that immediately makes footage look more cinematic and professional. I tested it during a recent shoot at a local restaurant with dim lighting and the results were amazing, all those point light sources got this dreamy halo effect that would have taken hours to recreate in post-production. The filter also does wonders for close-up shots of people by naturally smoothing skin tones without making everything look artificially soft.

What surprised me most is how well the anti-reflective coating works, I expected some issues with flare or ghosting but even shooting directly into bright windows didn't cause problems. The build quality feels really solid too with smooth threading that doesn't stick or cross-thread when mounting. For anyone doing portrait or narrative video work, this filter adds so much character that you'll wonder how you managed without it.

I tested this Black-Mist 1/4 filter in several sessions both indoors and outdoors, and the change was evident from the first shot. The image gains a more cinematic look, with diffused lights and smooth transitions that give it a professional touch. In portraits, it helps to soften the skin naturally without losing detail in the eyes or in key areas.

The assembly was simple thanks to the brass frame, which is screwed together without looseness or strange friction. I've used it in night recordings and in shots with strong lighting, and it achieves an interesting balance between softening reflections and maintaining overall contrast. In addition, the coating really prevents fingerprints or drops of water from accumulating, which is very useful if you work outside.

I ordered the Neewer 82mm Black Mist 1/4 filter for my Nikon lens and think it is well made. The filter fits perfectly and the housing around the glass is made of brass.

I also like that the filter is delivered in a narrow, sturdy storage box and storage case. This allows you to pack it away and transport it well protected. By the way, the box can also be used as a picture frame. I think that's a good, modern and stylish idea.

But back to the real thing. With the filter, the lights in the background look a bit more diffuse and get a slight glow. This creates an atmospheric atmosphere, which I really like. I mainly use the filter for portraits.

I was impressed by my new lens accessories and I like to use them. I've earned five stars.

I've been using the Nano series of K&F filters for the past few years, and have found them to be in the top tier of filters. (I'm also someone who has at least a "protection" type filter on my lens almost all the time.)

This is a fairly subtle filter; I think you could come close to simulating what it does with some careful tweaking in your photo editor—but I'm not quite sure about that. It has a VERY gentle softening effect, but does this without adding a "haze" like most diffusers do—so it has a bit less of a halo quality on highlights, if that makes sense. Colors don't lose saturation. I also think this makes it pretty useful. I think I might be happier with a 1/4 rather than the 1/8 effect that I bought—but that's not to fault this glass.

The past few years most of my "serious" shooting has been medium format, and at times the detail levels, especially on people, can become problematic. Diffusors can help soften the image, and often also effect the contrast; black diffusion has less effect on the contrast.

As with the other K&F filters I've been using, the ring is nicely machined, and threads very easily. Being from the PRO line means this also gets the ring in brass, which gives the filter the weight that the nice German filters I used to always use had. And brass does feel even smoother than the aluminum typically used. It also comes with a very nice fabric and suede case. Coating on these are top notch.

The build quality is excellent, solid metal frame, smooth threading, and the glass looks crystal clear with great coatings. It feels like a premium piece of kit without being crazy expensive. What I love most is the effect. I went with the 1/8 strength, and it’s perfect for softening up those ultra-sharp digital images without making things look muddy. Highlights bloom just enough to give that cinematic vibe, and skin tones look super flattering. It’s subtle, but it makes a big difference, especially for interviews, portraits, or any creative shots where you want a little mood. The case is a nice bonus too, sturdy with a magnetic flap, so it’s easy to toss in your bag without worrying about scratches.

This K&F black mist filter is awesome - The optical clarity is really good and it comes with a nice, plastic-free case to keep the lens in. Black Mist filters are great to create a nice and soft cinematic look. The body is well machined. From previous experiences with this brand, their customer support is awesome and their products last a long time - I still have lens filters from 5 years ago that work like new! They're pretty scratch resistant as well. I would honestly not choose anything but K&F concept lens filters at this point, they make awesome stuff and I'm really happy about receiving this - I can confidently recommend this!

With its Black Mist effect, this filter provides soft lights, reduces harsh contrasts and gives your pictures a dreamy, slightly foggy atmosphere — perfect for atmospheric portraits or cinematic shots.

Thanks to the ultra-low reflection and the high-quality multi-nano coating (Nano-Xcel Pro), the image quality remains clear and free from annoying light reflections. A must-have for anyone who wants to add a special look to their photos and videos!

This 77mm black diffusion filter adds a subtle mist effect that elevates portraits, vlogs, and cinematic shots. The 1/8 strength is just enough to bloom highlights and soften skin tones without sacrificing detail. It’s ideal for creating mood without muddying the image—especially in natural light or low-key setups.

The build quality is excellent, with 36 multi-layer coatings that resist glare, fingerprints, and minor scratches. Threading is smooth, and the filter seats securely on lenses without shifting. If you're looking to dial in a dreamy aesthetic with pro-level control, this XPRO series filter delivers nuanced diffusion in a durable, well-engineered form.

I mainly use the filter for video recordings with fixed focal lengths, and it provides exactly the effect I was hoping for: soft contrasts, slight blooming in light sources — all without being excessive.
