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.

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 like diffusion with a light touch (any type). Mist diffusion filters in particular tend to become increasingly problematic looking as they get stronger. The K&F filters work well and are value-priced. Keep the effect targeted with a light touch and you'll be quite happy with them.

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.

For the price, I was pleasantly surprised by the result!

I'm really happy with the K&F Concept 62mm Black Diffusion 1 4 & 1 8 Lens Filter Kit. The filters are a great addition to my camera bag and have already come in handy. The mist cinematic effect filter is perfect for vlogging and portrait images, and the black diffusion filter helps to create a more cinematic look in my photos. The quality of the filters is great, and they're easy to use.

I've been using a smaller-diameter K&F Concept Black Diffusion 1/4 with my 35mm prime, now I've got this larger 77mm-diameter set for my Sigma 17-50mm f/2.8. I live near the water and I really enjoy the way these expand highlights from the opposite shore.

happy with these! Great quality
