Excellent Filter for Softening Light
The K&F Concept 72mm Black Diffusion 1/8 filter is great for adding a soft, cinematic look to your photos or videos. It subtly diffuses light, reducing harsh shadows while maintaining image clarity. A solid choice for photographers and videographers looking to enhance their shots with a smooth, professional feel.

I love the effect that the filter gives, it softens the texture of the skin and generates a little haze that gives a cinematic image to the videos, excellent filter

K&F is really making some fantastic filters as of late. The build quality on these are excellent. Precision machined brass rings that are thin enough not to interfere with the image but strong enough to protect your glass. They screw on very smoothly and the brass will prevent stripping and cross threading. The optical quality of the glass is excellent. There is no distortion whatsoever and the mist filter gives your images a very subtle dreamy quality. Something really impossible to do in Photoshop or with digital editing in my opinion. You get the realism and quality of an actual optical effect, and these look absolutely beautiful. Some people may disagree but I always prefer doing as much as you can in camera to eliminate the need for post processing. And of course for video it’s definitely a timesaver. Applying this subtle mist effect digitally in video is very processor intensive. This is a nice little way to soften the features for portraits and I decided to take a portrait of this little fellow. You can really see the difference around the eyes that the filter makes in addition to the fact that it was really bright and this filter helped soften the shadows. This is a 1/4 Mist so the effect is very subtle. Don’t be confused by the name black diffusion. This filter will lighten your images by reducing contrast and softening highlights. It actually lightens up the image a bit but in a way that doesn’t create blurriness. That’s the beauty of genuine optical filters rather than digital post processing effects. This is comparable to my German filters that I paid a lot more money for in the past.

Just about every lense accessory I've purchased in the last year or two has been from K&F.

All have been top notch, Now i wouldn't know what the difference between this, and a filter thats like 10 times the ask, but these all work perfectly for me.

This lense I would describe as a very Hollywood Noire like look, Its a very heavy look. @ 1 vs the quarter and eighth
I like the texture on the filter, makes it so you dont have to fight to get the filter off

Overall everything i've bought from K&F has been perfect, and done exactly what it says for me at my experience level

first test of the black diffusion 1/2 filter

The strongest diffusion filter I own. This filter makes images absolutely glow pair this with some super sharp glass and you have a recipe for images that look like scenes to a film.
The filter is well made and boasts a heavy diffusion coating.
This is perfect for portraits or video projects.

This is great value in my humble, beginner opinion! Introduces a nice bloom effect with a decent light source. Build quality is of high standard and the glass is quality as well! I would say this is a bit more than 10%, but does the job very well either way. Shots taken on my new Fuji X100vi

Nice I really recommend

I’ve been using this filter on my Rokinon 16mm cine lens mainly at concerts that use hazers and I am truly loving the results. Screws on easily and no issues with unscrewing to remove. No color shifting, but this is definitely a stylistic look so apply it wisely.

Very good quality and results
