K&F has become my go to brand when looking for filters and this bit of kit is at the top of their line of quality filters. K&F have filters at just about every price point but this offering is at the top of their line. You can tell by the packaging that this is one of their best and it carries a price point along with that. We are at a point with digital photography/videography where image quality is almost too crisp and detailed. Black mist filters help soften the image a bit and come in numbered (fraction) values in terms of how much diffusion they provide. This filter is in the middle of the diffusion scale at 1/4, it provides a reasonable amount of softness (not too soft) that is noticeable over the unfiltered image. Black mist filters are best for portrait and night photography. If you are a professional photographer/videographer this is a black mist filter you should consider, if you are passionate about your hobby this set will appeal to you as well.

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.

I ordered this UV filter, part of the "Nano-X Series" by the K&F CONCEPT brand, and in the 46mm lens diameter to attach on my 50mm f/2.0 Fujifilm lens. I didn't have a good UV choice yet for this lens, and so far I have no issues with this filter at all.
This brand matches the quality both in terms of effect it produces, and also the quality of the aluminum casing and glass itself, I honestly see no difference between it and more prominent brands. This was an easy choice, as I have trusted the K&F CONCEPT brand for a variety of photographic tools to date.
Easy to install and remove, provides great lens protection. I will be a returning buyer from this brand. 5 stars.

The K&F Concept UV filter in 95mm is being reviewed.
I already own several UV filters from this manufacturer, along with all sorts of other accessories for cameras, lenses, action cameras, etc.
I've always been very satisfied with the quality offered, which is why I decided to buy a UV filter for my new super telephoto lens.
Thanks to developments in lens technology and digital sensors, UV filters now serve more of a protective function than a practical purpose. The lens coating is a sensitive part of the lens that requires special protection. With a screw-on UV filter like this, you don't change the look of the image, but you do have a layer over the coating due to the additional glass in front of the lens. For this reason alone, it's worth screwing on a UV filter. These days, they fit so precisely that you can also attach standard lens caps to them.
In my opinion, the K&F filter is of impressive quality. The glass is free of any inclusions or color casts, the screw-on filter is made of metal, and it comes with a plastic case and a microfiber cloth as a free gift.
Priced at just under €64 for a 95mm lens, it's also reasonably priced compared to the competition.
I'm therefore giving it 5 stars and hope my review was helpful.

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.

This is a superb filter. On the lens it is almost impossible to see if the filter glass is there, it is so well engineered.
It gives clear and crisp results whether wide angle, telephoto, sunlight, indoors, outdoors or whatever. There does not appear to be any flaring, purple fringing or vignette (more to do with the relative size of the filter and lens though).
I would say this filter is top class and can recommend it to anyone who needs a good filter for high quality / professional work. It is quite expensive but I guess you get what you pay for in this case.

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.
