So I think a lot of folks involved in video product are very familiar with the Tiffen Black Pro Mist filters. This is K&F's version of that filter. I will go into what I think about the filter but you can also judge for yourself in one of the pictures in this review where I show you the same image; the first without the filter then with the filter.

One of the results you get with a filter of this type is blooming of the highlights. This filter does quite a good job of that. Comparing the bloom to the Tiffen line I would say it falls between Tiffen's 1/2 and 1/4 strength with it being closer to the 1/4. The highlight fall of was strong but natural in my opinion. Keep in mind the light in the image fills the frame so you are seeing this particular effect of this filter at it's most extreme. You won't see that much blooming in a more natural setting. Take a look at the highlights on the camera. To me the K&F filter had a great effect on the highlight roll off which was very smooth.

The other effect you get with a black mist filter is the slightly reduced contrast and the slight softening of the shadows. To me I thought this filter did this quite well. If you look at the texture on the handle of the camera in the image you can see how it's just sort of softened that texture. Imagine shooting a person and you can imagine how much you would be able to smooth out the skin.

It also comes in a nice little screw together plastic case. Inside the case are these little rubber stopper than prevent the filter from sliding around in the case. I love the attention to detail here.

So compared to the Tiffen version of this lens at the size I got which was 82mm the K&F Black Mist is about $40 cheaper. I think you are getting a lot of value for your money here. I can't wait to try out this filter on some upcoming shoots.

I think K&F is making a move into higher end filters and if this filter is an example of the kind of quality they can produce, I can't wait to see what filter they release next.

Black Mist filters are designed to give a dreamy look to pictures and especially video by creating a 'glow effect' to the whole picture. The hard edges of the picture will be softened but the contrast of the dark areas will be mostly retained. For the best effect you want to use this filter especially around light sources. A subtle glow will be added around the light spots.

In the box you get the filter and a slick carrying case that can also hold other filters at different sizes. This filter produces some gorgeous shots and it is on par with many other filters that cost more than this one.
The strength of the effect from this 1/8 varies depending on the scene, although it can be quite dramatic in certain situations comparing to those from other 1/4 filters. But with all said and done this particular strength is pretty much in the middle. It is never too much and it is never too little. Great filter.

Net als bij de dure Pro-Mist-filters, geeft dit video's en foto's een meer filmische glans door een lichte waas aan het beeld toe te voegen; het filter geeft de highlights een mistachtig effect zonder afbreuk te doen aan de scherpte en maakt ook huidtinten gladder. Al met al een mooi filter dat past en de camera beschermt en beter verkrijgbaar is dan het gebruik van een goedkoop UV-filter. Het glas hecht niet aan olie of vingerafdrukken, waardoor je het niet de hele tijd hoeft af te vegen.

Similar to the expensive Pro-Mist filters, this gives videos and photos a more cinematic sheen by adding a slight haze to the image; the filter gives the highlights a fog-like effect without compromising sharpness and also smoothes skin tones. Overall nice filter that fits and protects the camera and is best available than using a cheap UV filter. The glass does not adhere to oil or fingerprints, so you don't have to wipe it all the time.

Bought for long exposure works well so far

Zeer geschikt voor het maken van foto's van zijdeachtig water. Glas en draad van goede kwaliteit zijn essentieel voor elke serieuze fotograaf.

I am generally satisfied with this filter from K&F, it enables light sources to be filtered at night and a pleasant atmosphere to be created during the day. I use it with Xpro-1 which is combined with movie playback from a digital camera.

K&F contacted me to test the new Black Mist filter.
It is a filter designed for videos and to give a "vintage" touch to the final result.
In short: beautiful result even for photography. It is a useful filter for portraits or for landscape or storytelling reportage. You do not lose sharpness and you get a much less "shot" light that also expands in the shaded area.
It is a filter to be used in photography with large apertures and which "tells" an atmosphere.

But let's start from the beginning.
Packaging / handling: In addition to the plastic box, the filter is inserted in a very resistant and protective snap-on case. The filter is screw-type (rightly because it was created for videomakers and in any case up to a diameter of 82). I would have preferred a cardboard box. But the case that you can see in the photo (the round one) is very useful and sturdy. The filter is resistant and fits well to all the lenses to which I have mounted it.

Technical review:
It has no dominant details, so it leaves the colors similar to the photo taken without a filter. Great!
It does not lose light, there is no need to increase the ISO when it is mounted. Great!
The sharpness in the details (and here comes the beauty) remains almost unchanged. You DO NOT lose sharpness in the areas in focus even if I would not use it in ultra-defined landscape photography, but for a storytelling, outdoor or portrait set absolutely yes.
Autofocus is unaffected by the filter, at least not on the Nikon D750 with fixed lenses.

Usage / Effect: it is a filter that gives a “glow” effect to photos, very particular especially for videos and for portraits in harsh light or backlight.
The highlights are dimmed but without becoming dull, moreover the light "enters" the shadows, giving a very soft "glow" effect. Great for portraits or to give a more dreamy atmosphere, it removes clarity from the image in high contrast areas.

In the photos you can see a couple of unfiltered / filtered comparisons, two portrait photos set and what comes to you.

Result in short: it is a filter that you do not think can enter your kit, but when it does it has such a particular result that you would try it in any situation. A must try!

Het zwarte mistfilter is bedoeld om foto's, met name video's, een dromerige uitstraling te geven door een "glow-effect" voor het hele beeld te creëren. De harde randen van het beeld worden verzacht, maar het contrast in de donkere delen blijft grotendeels behouden. Gebruik dit filter voor de beste resultaten, vooral in de buurt van de lichtbron. Rond het lichtpunt is een subtiele halo toegevoegd.

Dit K&F Black Diffusion Filter is een uitstekende kit. Het vermindert het contrast, maakt de zwarte tinten wat grijzer en zorgt voor een zachte bloei rond de highlights. Er zijn vier filtersterktes beschikbaar; van zwak tot sterk, ze zijn 1/8, 1/4, 1/2 en 1.
