This diffusion filter has been on my camera since I got it. It's pretty excellent in the way that the diffusion is subtle enough that it's not overpowering yet adds an overall softness to the image and gives a rays of light graduated fall off. The filter pairs perfectly with FujiFilm cameras and all of their film simulations. It also feels very high-quality as the ring is made of metal, glides smoothly as you turn it and has very optically clear glass. I've tried a lot of this brands products and definitely believe they make great stuff.

This K&F Concept 1/4 Black Mist CPL filter has been a great addition to my photography kit! I primarily needed a circular polarizer, but the added mist effect has been a pleasant surprise. It fits perfectly on my 67mm lens, and even better, my lens cap fits snugly over it, so I can leave both on without any issues.

The CPL works as expected, cutting down reflections effectively. I tested it at a 45-degree angle to a window on a bright day, and it significantly reduced glare. While no CPL is 100% effective at removing reflections, this one performs just as well as some of the pricier options I’ve used before.

The built-in 1/4 Black Mist adds a subtle, dreamy quality to my photos, especially around bright lights, creating a soft, cinematic vibe. It’s perfect for portraits, as it softens skin in a flattering way. I did notice some detail loss, which might be a downside for those aiming for super sharp images, but the overall effect is beautiful, especially for creative shots.

The filter is slim, lightweight, and has a nanocoating that keeps it clear of scratches. The 2-in-1 design is super convenient, reducing the need to stack filters and risk losing image quality. It’s held up well during my shoots, both in hazy conditions and near water, where it really helps manage harsh reflections.

Overall, this filter is versatile, well-made, and offers great value. Highly recommend it for photographers looking to add a cinematic touch to their shots!

My experience with this lens filter so far has been quite positive. The lens so far came in handy for multiple scenarios, and that is what I was hoping for. The effects are perfect when in focus, especially the mist filter.That filter really needs to be done right, doing too much just seems unnatural later, unless that is the goal. Mist filter was not my primary reason for the filter though, it was for the reflections I get near water and in glass. The ones in water tend to blow out my highlights, ruin the image completely if I don't make the corrections, we all know that feeling. This is the perfect response for that.

Perfect thread fit, clean, no issues with lens or result in images taken.

Comes with cleaning cloth and case for the filter.

I have a few filters from all brands and price points, and these K&Fs really punch above their price point and run with the top European and Japanese brands. The glass looks perfect and the fit and finish are just as good as those costing many times more than these.

You do have to be a bit careful about mist filters because it's hard to tell on your camera how much diffusion you are getting. There is a sweet spot in focal length and aperture that will give you that softened look without looking out of focus, but it's also dependent on other factors like lighting direction and intensity, so it's not the same sweet spot for every shoot. You really need to shoot with these in more controlled environments where you can review the results on a bigger screen before committing your whole shoot to being behind a filter, that or duplicate shots without a filter. This particular filter is awesome near the water where the reflection can make shots extremely harsh and blow out parts of your image. I also got some good results in hazy weather to increase contrast without harshness. To be honest, you can duplicate most of the misty effect pretty easily in post, but knocking down harsh reflections is not as easy because those areas are most likely completely blown out, so this filter will help with that.

The K&F Concept 77mm filter is a solid choice if you’re looking to add a little extra flair to your photography or videography. The combination of the Black Diffusion 1/4 and Circular Polarizing filters really helps create a smooth, cinematic look, especially when you’re shooting portraits or landscapes. The diffusion effect softens the image a bit and gives it that dreamy, film-like vibe, while the polarizer cuts down on glare and enhances colors, making your shots pop.

The 18-layer coating is a nice touch, providing better clarity and helping to reduce reflections and smudges. It’s also built pretty well, feeling solid but not too heavy. The filter screws on easily and fits securely, so you don’t have to worry about it coming loose while you’re shooting.

Overall, this filter is a great tool for adding more creative control to your shots, whether you’re a professional or just getting into photography. It’s a bit of an investment, but if you want to elevate your camera gear and get that cinematic look, it’s definitely worth considering.

I have worked with K&F Concept filters and camera accessories for a few years and the large majority of my experiences with their products has been positive. I needed a CPL filter for a relatively new-to-me lens, so I had good expectations of this one. I have not worked with it long but so far I have had good results with it.

This is more than just a CPL filter but also a black diffuser and softener. I was primarily interested in the circular polarizer, though having other features is not unwelcome. My lens has a 67mm thread size, so I selected that size filter and it fits perfectly as expected. As a bonus to me, my lens cap fits snugly on the filter too so I can leave my filter and lens cap on the lens together.

In testing I pointed my camera at a 45-degree angle to a window in bright sunshine, and I was picking up all kinds of reflections. I turned the filter ring and the reflections faded out completely. On another surface at a different angle it softened the reflections but did not completely fade them out, but enough to make a noticeable difference. I have not found a CPL filter that is 100% effective at removing all reflections but this one does just as well as more expensive ones I have used with other lenses.

I have not experimented with the diffuser traits of this filter yet.

The filter comes with three microfiber cleaning cloths which are always useful.

I am pleased with this filter and will be using it more in the coming weeks. It fits my lens perfectly and so far it has worked well.

The filter is delivered securely packaged.
The build quality is very good, and the filter fits easily and precisely onto the lens.
The filter enhances the colors in photos, making the entire image appear more vibrant.

I have come to rely heavily on K&F Concept filters and wares. Their quality is excellent and, as with this lens filter, are definitely forward thinking/looking in their product offerings.

The 77mm filter I received is super cool.. mating up a circular polarizer (CPL) and a 1/2 black mist filter to deliver some softened dreamy images! The result of the filter is on the more subtle side softening some details and features. You will lose sharpness in your images but that's sort of the point..

The CPL is excellent and easy to use - spin the rotating portion of the filter to get the desired effect. The filter ring is manufactured in such a way. that turning the filter is effortless and easy on your hands (doesn't feel like you're spinning a hacksaw!). Installation is a breeze - the machined screw bezel is perfect and screws on oh so smooth!

NOTE: Do not over tighten filters!

The images would be great for senior portraits or even environmental portraits. I wouldn't use for a lot of commercial work as they typically want everything (at least the subject) to be tack sharp... but for some of my freelance or more creative work this filter will be a huge hit!

Let's say that this filter performs a double function in one object.
Very light, with a well-made ring.
The lens is truly top.
Mounted it does not make you lose slowness in the autofocus measurement and reduces the light by 1/2 stop (to be really picky).
In any case, it produces effects that are not very marked, but visible from the first print without resorting to post-production.
