The nano X pro series is head and shoulders above the rest of K&Fs filter line up. The build quality is super premium. The feel fit and finish compete with the likes of Polar Pro and are slotted in above some of their contemporaries.
The grip around the edges of the filter is well defined and the threads are pristine and smooth.

In line with expectations, very good workmanship. Gives the expected effect (sky contrast especially for me)

The filter fully met my expectations. The workmanship with the brass socket is first-class and the thread runs as smooth as butter. Screwing and unscrewing is easy every time.
The black mist effect gives my recordings exactly the cinematic look I was looking for. Highlights get a nice glow and the sharpness is pleasantly reduced without losing details. The nano coating works excellently - no annoying reflections even when backlit. For creative photo and video recordings, this filter is a real highlight.

Hello, 67 MM black diffusion 1/4
filter allows you to soften the brightness, and in particular on high brightness. This gives your photos an atmospheric effect, On the videos, the rendering will be more “cinematographic” and on the photo and in particular the portrait the skin will be smoother and the rendering more pleasant, It is for me a very practical filter that avoids spending a lot of time in post-processing.
Although its price may seem high, it offers a good alternative to “higher-end” filters, in fact the glass is Japanese (a guarantee of quality in my opinion).

For a portrait and night street project, I wanted less “digital hardness” in the pictures — that's why I ordered the Black Mist 1/4 in 72 mm.
After two weeks of use, the first thing you notice is the workmanship: brass frame, grippy milling, the thread runs smoothly and the filter sits flat on the lens. The flat profile is also nice; the original lens cap fits further on.
The 1/4 effect is clearly visible: highlights get a subtle glow, skin becomes a bit softer, contrasts look more pleasant. In bright daylight, it can be a bit “dreamy” — for architecture or very detail-critical motifs, I prefer 1/8.
Positive: hardly any reflections or color stitches, the nano coating is really easy to remove fingerprints, and the case is practical when out and about.
All in all, the filter quickly delivers the cinematic look that I would otherwise build longer in the mail. Not a bargain in terms of price, but the effect and workmanship justify it for me.

Very good quality Black Diffusion 1/4 Filter from K&F Concept made from very good materials.
I have been using this filter for just over two months and so far I have had no issues it works and works extremely well you get that soft and creamy look to your images of course you need good lighting to get the effect. This filter will help take your images to the next level.
The filter is thin and lightweight which is great BUT due to it being so thin there has been a few times when I have struggled to get a good grip to unscrew the filter from my lens I have always gotten it off so this is not a game changer for me personally. With the filter on it is still 77mm so your lens cap/cover can still fit so you can leave it on if you want to when not using the camera.
Comes in a very nice stylish material case good stitching which gives this a professional look and feel, has magnet in the case which is used to close the lid/case these are all very nice touches.
Overall I am happy with the Black Diffusion Filter I feel it is a fair price and I would recommend it.

I generally find all products from K&F Concept to be of great value and this Black Mist 1/4 filter is no exception.
I got the 77 mm version and paired with my trusty Nikkor Z 24-120 F/4.
The manufacturing quality is at such a high quality that you don't have to think twice when ordering: brass socket, strong thread, no wobbling whatsoever. Unscrewing and unscrewing is as smooth as butter, every single time.
As for the filter itself, its effects are immediately noticeable: it reduces the sharpness from digital cameras, reduces skin blemishes and gives highlights that subtle, cinematic glow. Except for edge situations, when the lights are overly bright or coming from certain angles, there are no image degradations when using this filter. No reflections between the filter and the lens' front element.
In broad daylight, the effects of this filter might be a bit too strong. The image can become a bit too dreamy. Then the less strong model, the 1/8 might be a better choice.

What can I say, K&F gives birth to this 1/4 Nano Xcel Pro black mist and it's crazy. A must-have filter because it gives a “vintage” paste to the photos by cutting the black areas and giving that slight glow that, especially with the lights, has a more cinematic appearance. Top quality and amazing results. Both on video and on photos the results are so good that I decided to leave it on the camera by default. K&F is always a guarantee and if taken in combination with the 1/8 one the pleasure increases dramatically. Especially on video you will see that muffled and smoky situation that is usually obtained by using the smoke machine to isolate the subject from the seabed.
Absolutely recommended.

Tested during a night walk in the city. The street lights get a soft halo that makes the scene more atmospheric. Sharpness stays where it's important.

I'm constantly amazed by the quality K&F has achieved, and this filter is a prime example.
The presentation is superb; you can even reuse the box as a picture frame!
