It is an excellent filter for the price and the quality it provides. In my case one 1/8 of 49mm. The effect it produces is really nice and I can say that even in the definition there is a better minimal but very interesting one. Recommendable.

I have tried, and own, different grades of black diffusion filter. I think for its subtle effect, this 1/8 filter is my favorite. The smooth look, and highlight diffusion that you get with these filters, is either an acquired taste, or a specific characteristic that you're looking for in your shots. I personally don't use them all the time, but it is nice to bloom the highlights in certain scenarios. The 1/8 filter is very subtle in the daylight, but I found excels at night. You can of course, use it with decent effect during the usual golden hours, as the intensity of the highlights then, may be more visibly changed by this filter, photographically. In the daytime, with the sun right above you, it's hard to notice much of a difference. For video, it does an interesting effect, and may be something that you can apply to specific scenes, or just to unsharpened some of the digitized look from most cameras. Quality of the filter is very nice, made of good materials, and with nice coatings. It comes well packaged, in your standard plastic case, as well as included sealed microfibre cloths. It is affordably priced, and performs very nicely, for that price range. It doesn't in any way appear cheap to me, and like mentioned before, I do like the subtlety of this gradient. It's certainly good for the camera bag, and would be interesting to try with some golden hour portraiture. For video, I'd say it's limited to dreamlike sequences, and better suited for golden hour, and night time. All in all, I'm very pleased, and if you're looking for a 1/8 black diffusion filter, this one is a good choice.

If you're looking for a filter to create stunning cinematic effects in your photography or videography, then the K&F Concept 77mm Black Diffusion 1/8 Filter is definitely worth considering. This filter is incredibly easy to use and can help you achieve a dreamy, soft, and misty look that will make your work stand out.

One of the standout features of this filter is its build quality.

Another great thing about this filter is that it doesn't have any negative impact on image quality. The filter is specifically designed to reduce the sharpness of your images slightly, which helps to create the dreamy, cinematic effect that it's known for. However, this reduction in sharpness is subtle enough that it won't impact the overall quality of your photos or videos.

The K&F Concept 77mm Black Diffusion 1/8 Filter is an excellent choice for anyone who wants to take their photography or videography to the next level.

The filter is also very durable and easy to clean, making it a great option for anyone who wants a high-quality filter that will last for years.

An excellent filter from a company I trust. K&F make superb filters and I own several of them. They're a step up from other filter manufacturers and it shows in their attention to detail.

This ⅛ black diffusion filter adds just a touch of skin-smoothing-softness to your images which is very flattering to women's skin and unnoticeable to most people; it just looks natural. Highlights only have a very slight halo around them and the contrast of your image will be only slightly reduced; the blacks won't be quite as black.

This all adds up to be a great filter when you are shooting portraits. And if you want more diffusion you can order stronger variations of black diffusion. See their Amazon description for a comparison of the different strengths of black diffusion.

This is a bit of a niche filter, but I like the effect it provides and it fits my lenses. There doesn't appear to be any negative effects of color casting. I'm glad I have it as an option.

You can’t go wrong with this filter if you need that filmic soft look I love it

K&F Concept Nano-K series Black-Mist 1/4 filter 67mm

The filter makes a good impression of quality. The effect is gentle and it gives the images a creative look. I tested the filter with the Tamron 28 -75 2.8 G2 and am satisfied with the results. The model's face is slightly blurred and saves time in post-processing.

Price - performance and image results are good.

An excellent diffusion filter. It looks more like a standard diffusion than a black diffusion. So you get the highlights to bloom but retain contrast.
And at 1/8th its not to strong for most situations.
Absolutely love these. K&F have another winner on their hands.

So if you are looking at this review, you probably already know what a black diffusion filter does. If not, then let me just tell you that it basically lowers contrast and makes the highlights bloom a little more than they usually do. It doesn't exactly soften the focus, but it does soften the overall image.

Now to the filter...K&F builds a well-constructed filter. I buy a lot of my filters from K&F, and they have never disappointed in terms of using quality material, a pleasing design that doesn't announce its presence on my camera lens, and glass that doesn't affect my very expensive optics. This filter provides about what I expect from a 1/8th Black diffuser (black mist) in terms of the overall effect. and you just really can't go wrong with anything that K&F produces.

So if you're looking to make lights bloom, without softening your portraits to almost unusable levels, this is the filter for you. It has definitely earned a place in my camera bag.
