Included in delivery: case and filter.
Tested with my Nikon kit lens. (see my sample photos)
Each top photo was taken on a tripod with a 10 second timer.
The Black Mist Pro filter has been added to each bottom photo.
This really works, as the name suggests!
You can see the colors and sharpness side by side in the original without a filter.
Then after you put the filter on the front of the lens,
you get a black fog. This calms the color saturation and the sharpness.
Just a small amount.

The case.
The top twists off the bottom and is made out of a smoke-colored plastic. The edges have a nice set of grooves.
Facilitates opening and closing. Branding above.
The bottom is made of the same plastic and has the same grooves on the side.
The highlight are the 2 gray silicone pads that are glued inside.
(These grooves will hold your filter) You can also use smaller and larger filters.
That's a plus.

The filter.
Is slim and made of aluminum.
The sides have really nice grooves which makes using the filter very smooth.
Great glass. Actually scratch resistant.
Got my keys out and hey, no scratches. Thumbs up.
Waterproof.
Filter weighs only 0.5 ounces. Both the housing and the filter weigh 2.7 ounces.

Overall very happy with the filter.
Great quality.
I took the 52mm version.
Used 2 of my kit lenses and no problems. Very easy to install and remove from the lens.
Easy to clean. Should last a very long time.

I prefer to shoot with filters rather than go into the software and spend extra time trying to get a similar effect.
Hope that was helpful.

So far, so good. It adds the right amount of haze to portraits to make it stylistic. It doesn't add too much in my opinion, and the image is still pretty sharp.

I've attached a test shot below that I took of a friend of mine in direct sunlight with a star filter and an ND filter (using this filter below).

The quality is there, the light and the faces are diffused as desired. Change and give a soft cinema look to all your shots! I have already tried cheaper filters but here I must admit that the filter does the job really well. Night shoots look better with it! At the top I recommend!

Nice filter. Certainly useful in certain situations. Ideal for sharp lenses, especially without character. That brings some mood into the game. It's nice to have, looks well made and I love that I can put it on a lens and still use the lens cover over the filter when not in use. I use it on my Sony 18-105 f/4 and Sigma 18-35 f/1.8 and am quite happy with the result. In my images, the last image is the one without the filter, hopefully you can get an idea of ​​what it does.

I bought this filter to get rid of the sharpness and overly digital look of today's cameras. The quality of this Black Pro Mist from KeF is excellent, the result is identical to the more expensive filters from Nisi.

The effect it gives is mainly apparent when we frame light sources that create a halo around the main source, be it the sun or an artificial light.

Great for adding a vintage and special touch to your photos/videos

As someone who works extensively in video production, I am very familiar with diffusion filters. I've been using them for a while for various projects. What makes this filter from K&F Concept so special, in addition to the great look, is the magnetic filter system. Having recently bought a few more different magnetic filters, I quickly grew fond of this concept and have almost completely switched.

The diffusion filter does exactly what it is supposed to do, no more or less. The filter will add tons of character to your digital images from your DSLR. The magic of the filter is that it literally makes the lights (especially light sources) glow. The effect adds a dreamy halo look to the highlights, a common look of feature film styles. I've attached a screenshot of a music video I recorded with the filter.

In the box you get the diffusion filter, an adapter ring and the lens cap. All of these items are magnetic and snap directly into each other. You simply screw the adapter ring into your lens thread and then snap the diffusion filter into place within seconds. You've got the gorgeous look you've been waiting for.

It is a filter designed for videos and to give a "vintage" touch to the final result. In short: wonderful result also for photography. This is a useful filter for reportage or portrait or landscape narration. You don't lose sharpness and you get much less "pulled" light that also expands in the shadowed area. It is a filter to be used in photography with large apertures and which "tells" an atmosphere. Technical review: It has no dominant details, so it leaves the colors similar to the photo taken without filter. Great ! It doesn't make light, you don't need to increase the Iso when you mount it. Great ! The sharpness in the details (and here is the beauty) remains almost unchanged. You don't lose sharpness in focus areas although I wouldn't use it in ultrafine landscape photography but for a storybook, outdoors or portrait together absolutely you. Autofocus is not affected by the filter, at least not on the Nikon D750 with fixed lenses. Use/Effect: This is a filter that gives a glowing effect to photos, especially special for videos and hard-light or backlit portraits. The reflections are lowered but without becoming dull, moreover the light "penetrates" into the shadows, giving a very soft "glow" effect. Ideal for portraiture or to give a more dreamy atmosphere, eliminates image clarity in high contrast areas. In the photos you can see some comparisons without filter / with filter, two portrait photos together and what comes to you. Bottom Line: This is a filter you don't think you could fit into your kit, but when it comes in, it has such a distinctive result that you try it in any situation. Absolutely to try!

Beautiful effects, especially for weddings and couple shoots. With a long focal length, I would take almost 1/8. Price performance is okay. One person found this helpful

This K&F Concept Black Diffusion Filter creates a very, very cool dreamy effect while maintaining image sharpness. I use it with my Fuji X-T100, and I'm very happy with the results. The filter screws on perfectly (no issues with the filter body) and does not create vignetting even when used on my UV filter. The images I take with the filter are nice and clear, but with the dreamy, slightly grainy film effect that haze filters like this are supposed to give. I love that I can get the effect without applying any filters while editing. The filter also gives a softer effect to faces, so it's ideal for portraits. I use the 1/4 filter, so the effect is soft. The greater the number of filters, the greater the effect produced.

I really didn't know what to expect from this filter. I mean I know what it technically should have done but I've been fooled before with poor quality results and not knowing this brand I was prepared to be disappointed but I certainly wasn't . This filter offers a wonderful softening effect that doesn't blur so much, but rather seems to maintain decent focus while creating a slight hint of haze. It's very delicate and a really nice tool to have in a portrait photographer's arsenal. It also has a pleasing effect on candles and sharp light points, creating a softened tint or aura around the light source. It sounds a bit "dreamy," if that helps paint the picture. I I've used this filter with my primary Nikon portrait lens and intend to continue shooting with it to learn more, but so far it's been a pretty exciting find. I will say that while safe enough, I find that this filter does not match my lens threads as precisely as I am used to. Something seems wrong but they're not binding so I'll leave it pretty much alone. I am very impressed with this filter and think it is reasonably priced. Really recommended.
