it is a little different when talk about the effect. Also easy to install and uninstall. Overall quality seems good to me. Like the combo.

I got these for my Sony 35mm f/1.4 lens on the Sony A7IV. The images from this setup is always sharp and that is not always the goal. So these filters come in handy to dial it down a bit. Depending on the scene you will need to increase or decrease the intensity of the softness introduced hence the two options which are my go to anyway. Great value product.

This set of camera lens filters are of excellent quality. I am very much an amateur and have only limited experience using filters and that was years ago when I was taking a couple of B&W photography courses with a 35 mm film camera. I do have two DSLR camera & lens kits which I have been experimenting with and when I saw these lenses I wanted to try them out. I am not as familiar with the Japanese-made glass used in these filters as I am with the German-made glass in the lenses and filters I used to have, but the optical quality of this AGC glass and the coatings seems to be top-notch. The filters are thin, light and strong, + they are also very clear with no imperfections noticeable to the naked eye. The light transmittance is very good, so even though I am diffusing the light, there is still enough. I really appreciate that this set includes both the 1/8 and 1/4 lens filters. I ordered the 58 mm version for my Nikkor zoom lens and both filters fit perfectly. i like that both of the filters have the external threads so I can also attach another filter over or under the one I am using. I haven't done that yet as I am still exploring what type of images I can get just using one or the other of the filters in this kit. The cases are very nice, as well -- they feel strong & sturdy. The current price of $69.99 for two lens filters seems very reasonable, and I will definitely look for this brand when I'm ready to try other types of filters.

I think people are sleeping on these K&F diffusion filters. I have been using these for some time and I have been really impressed with them. In fact I see little difference between these and the Tiffen Black Pro Mist filters that cost a heck of a lot more. I mean think about it...these are diffusion filters. They aren't supposed to be perfect. They are meant to give your image a softer look by diffusing the light a bit. They provide some nice bloom to the highlights as well.

The 1/8 strength filter is a great all around filter that I use for a lot of my shoots. I only go to the 1/4 strength one when I am looking for that really dreamy look.

Diffusion filters are a great tool for softening skin and "blooming" highlights. They can minimize the "digital video" look and yield a "cinematic" (sorry, I have to use that term) quality to otherwise overly sharp images. Unlike the old, messy trick of smearing grease on a clear lens, mist filters will retain detail while also softening. Seems contradictory, but once you try it you will see what I mean. The effect can dramatic in high contrast lighting with practical lights (visible in frame). The effect is less visible in flat lighting, but can still be effective.

Unlike neutral density filters, black mist diffusion filters typically do not impose a color cast. From my testing, the K&F Concept filters are neutral and work very well, especially for the price. The 1/8 is fairly subtle, and holds detail well. The 1/4 is stronger and what I would most likely try first, but does obscure some fine details. Note that diffusion tends to become more pronounced when shooting with a longer lens, or small aperture. So, testing and a good monitor is always necessary.

These filters have a nice grip to the outer ring, which makes installation and removal easy. They are threaded on the front if you decide to stack other filters in front. They also ship in a nice cary case, although I transport my collection of filters in a large filter organizer.

For the price, these filters are a great value, and well worth having in any videographer's tool kit.

People often ask me what my secret is for the warm look of my educational videos. Well, the 1/8th filter is it.

I have been using diffusion and mist filters for years and when I needed to get a full time diffusion filter for my two 77mm lenses, I didn’t want to pay the exorbitant prices of the bigger name brands. Having used other K&F filters and being satisfied with the quality, I thought I’d give these a shot.

I’m glad I did. These are at least as good and perhaps even better than the others I have. The 1/8 diffuses lights and specular highlights with a very pleasing, subtle softness. It also smooths the face a bit and makes small blemishes, wrinkles, and imperfections barely noticeable. It is a subtle filter versus the 1/4.

The 1/4 is of the same quality, but a far more intense effect. I’m glad I have it and have had a chance to use it on multiple occasions for creative, dreamy shots. That said, the 1/8 is a workhorse and I use it all the time.

If you’re considering these versus the more expensive brands, worry not. These are excellent and get the job done.

Very well protected filters, they adhere to the lens perfectly. Recommended

The K&F Concept Black Diffusion are excellent examples of a filter type that's a little misunderstood by some people, I think, as to what it can accomplish and do. The filters come in various strengths, and at the strong end of the range can produce results that look like diffusion. That might be useful sometimes for still photography. But the real use for these filters is at lower strength (1/8 and 1/4) for video. When used that way they can both subtly reduce contrast, reduce highlight burn and smooth skin. They won't work miracles. But if your scene is well lit and involves a person speaking to the camera or otherwise being face on to the camera these filters can subtly smooth skin and reduce imperfections. The effect is more noticeable with video shot using log profiles and gamma, to be graded in post production, but shows results even with standard color and camera profiles. I have a whole set of these filters in various sizes just for shooting face to camera subjects, talking heads, etc. There are several manufacturers making variations on this type of filter but the K&F Black Diffusion filters have been outstanding.

I'm thrilled!

I only did a short test with my mobile phone after unpacking, but I am convinced that I can shoot really cool portrait and wedding party pictures with the two filters.

Qualitatively, there is nothing to complain about, the diffusion grains look even and good. The filters can also be screwed on perfectly. Attached is a comparison picture, shot with my Sony A7IV at 85mm f1.8

I'm really loving the K&F concept diffusion set, it gives the wonderful haze like effect with halides on the lights and bloom to really give you that dreamy film like aesthetic. The great thing about it is that it also doesn't lower the quality too much of your images. It get's rid of that "clinical" sharp digital look and adds life to your photos. The packaging is great albeit a bit large for the filter itself but it's a nice little carrying case to put into your bag.
I love using the 1/8th strength for everyday shots and the 1/4th when you really want to amp up the dreamy look.
