I recently got the K&F Concept 67mm Black Diffusion Mist 1 4 Effect & Variable ND2-400 (1-9 Stops) ND Lens Filter and it is incredible! This filter has adjustable levels of density, allowing me to get the exact effect I'm looking for. Not only that, but it's multi-coated with 28 layers of Nano-X Series and made with high-grade materials that feel sturdy.

The K&F Black-Mist Filter is my first filter that creates an effect. I haven't had any experience with this and to be honest I'm very pleasantly surprised. Of course, this can look completely different for someone who already has experience in this area. The filter is delivered in the folding box familiar from K&F. In addition to a plastic box in which the filter is packed again, there are 3 welded-in microfibre cloths to make the filter and the lens dust-free before assembly. What I personally really like is the coating of the metal ring. Filters are often painted very smoothly and are difficult to tighten. A matt and very non-slip coating was chosen here. The grip is further supported by 2 zones with corrugations and you can tighten the filter very nicely and without any problems. It would be whining at a high level if you now wanted to add a better fitting storage box for the filter. There is nothing wrong with the fit and the smooth running of the thread. Therefore I award 5 out of 5 stars.

K&F Concept 1/4 Black Mist Diffusion 67MM Filter

Super cool filter, well made and good quality. The filter can be screwed on cleanly and sits perfectly on my Tamron's 28 75 and 70 180 2.8. The effect is really cool and in combination with the Aputure Accent B7C, Hollywood says hello.

I think the filter is really cool and you can let your creativity run free. The price is also great and super fair.

The 1/4 Black Mist Diffusion Filter from "K&F Concept" (never heard of) arrives at home well protected in a filter box. I ordered this filter for my Canon FD 50/1.4 ssc (filter diameter 55mm) and what I noticed right away was that the filter hesitates when I try to screw it on....this can then be a bit of a game of patience, but you have it sometimes once the start of the thread is caught, it can be screwed on without any further problems. The image quality is not negatively affected by the filter, it just becomes a bit softer (dreamier), mainly when light is involved. I could still show pictures of my daughter (from my hobby studio) with light from behind, but you're not allowed to anymore. I think you can see what the filter does from the two pictures I posted. If it weren't for the fumbling to screw it on, he would have gotten all 5 from me, so it's still a very good 4.

The black mist filter is designed to give images, especially videos, a dreamlike look by creating a "glow effect" for the entire image. The hard edges of the image are blurred, but the contrast in the dark areas is largely preserved. For best results, you need to use this filter, especially near the light source. A subtle halo is added around the point of light.

I have a Black Mist Pro 1/8 filter that I use quite a bit, but wanted to try a 1/4 for a more pronounced "bloom" in conjunction with a dream sequence I was shooting. I have the K & F 1/4 Black Diffusion Filter for about 20% less than the cost of a Black Mist Pro so thought I'd give it a try. I have used K&F filters before and have always been happy with them, although they are perceived as lower quality filters by some "professionals". I'm happy to say that the K & F is just as good as the Black Mist Pro equivalent and achieves exactly the desired effect with no distortion or color cast. And if you consider the magnetic docking system, I would say that it's even better than the Black Mist Pro filter (this is the first magnetic filter I've used and I'm hooked). This filer is excellent value for money.

I have the Olympus OM-D E-M1 Mark II which is a Micro 4/3's camera. As such, the lenses are tiny with less glass to cover, making the price of these filters extremely low. So I bought both this K&F Concept 58mm Black Soft Filter 1/4 and the infamous Black Pro-Mist 1/4 Filter. This is all subjective, but I prefer the look of the Tiffen black pro mist more. The K&F is a bit too bloomy, and the image loses a lot of contrast. That makes the K&F less versatile. Meanwhile, the Tiffen is more balanced, with less bloom and higher contrast. Making it perfectly acceptable for everyday use.Given the low price of this K&F filter, I'll still keep it. But, If I had to choose one, it would undoubtedly be the Tiffen Black Pro Mist filter.

I have a Black Mist Pro 1/8 filter that I use quite a bit, but wanted to try a 1/4 for a more pronounced "bloom" in conjunction with a dream sequence I was shooting. I've seen the K&F 1/4 Black Diffusion Filter for about 20% less than the cost of a Black Mist Pro so thought I'd give it a try. I've used K&F filters before and have always been happy with them, although perceived as lower quality filters by some "professionals". I'm happy to say that the K&F 1/4 Black Diffuser is every bit as good as the Black Mist Pro equivalent and achieves exactly the effect I was looking for with no distortion or color cast. And if you consider the magnetic docking system I would say that it's even better than the Black Mist Pro filter (this is the first magnetic filter I've used and I love it). The price/performance ratio for this filer is excellent.
