As someone who works extensively in video production, I am very familiar with diffusion filters. I've been using them for a while for various projects. What makes this filter from K&F Concept so special, in addition to the great look, is the magnetic filter system. Having recently bought a few more different magnetic filters, I quickly grew fond of this concept and have almost completely switched.

The diffusion filter does exactly what it is supposed to do, no more or less. The filter will add tons of character to your digital images from your DSLR. The magic of the filter is that it literally makes the lights (especially light sources) glow. The effect adds a dreamy halo look to the highlights, a common look of feature film styles. I've attached a screenshot of a music video I recorded with the filter.

In the box you get the diffusion filter, an adapter ring and the lens cap. All of these items are magnetic and snap directly into each other. You simply screw the adapter ring into your lens thread and then snap the diffusion filter into place within seconds. You've got the gorgeous look you've been waiting for.

I ordered the 55mm Black Soft Diffusion 1/8 Effect Filter to use with my Nikon D5600. I'm a beginner but I enjoy the effects of this filter, especially in daylight. The effect is subtle but effective. There is a nice bloom and minimal color variation. No loss in image quality observed. Thread on the filter makes it easy to screw onto my camera lens. Came well packaged. Useful filter to have a variety of settings at hand.

Great price.

Similar to the expensive Pro-Mist filters, this gives videos and photos a more cinematic glow as it adds a slight haze to the image. The 1/8 is lighter than the 1/4 filter size and always has the 82mm thread size as you can get step up rings to fit the filter. The filter gives the highlights a fog-like effect without sacrificing sharpness and also smooths out skin tones. Overall nice filter that fits and protects the camera and is best to have than use a cheap UV filter. The glass won't stick to oil or fingerprints, so you don't have to keep wiping it down.

This K&F Black Diffusion Filter is an excellent kit. It reduces the contrast, makes the blacks a bit grayer and provides a soft bloom around the highlights. Four filter strengths are available; from weakest to strongest they are 1/8, 1/4, 1/2 and 1. This 1/8 filter is the weakest, but it still makes a noticeable difference in the look of the pictures you take with it.

The Black Mist filter is designed to give images, especially videos, a dreamlike look by creating a "glow effect" across the entire image. The hard image edges are softened, but the contrast in the dark areas is largely retained. For best results, you must use this filter, especially near the light source. A subtle halo is added around the point of light.

Includes: case, and filter.
Tested with my nikon kit lens. (see my sample photos)
Each Top photo was taken on a tripod with a 10 second timer.
Each Bottom photo, the black mist pro filter was added.
This really does work as the name suggests!
Side by side you can see the colors and focus in the original without filter.
Then after applying the filter to the front of the lens,
you get a black mist. This calms down the color saturation and the sharpness.
Just a small amount.

The case.
Top twists off from the bottom and is made of a smoked plastic. The edges have a nice groove set.
Makes opening and closing easy. Branding on top.
The bottom is made of the same plastic and has the same grooves on the side.
The highlight is the 2 gray silicone pads that are glued down inside.
(These grooves will hold you filter) You could also use with smaller and larger filters.
That's a plus.

The filter.
Is slim line and made of aluminum.
Sides have really nice grooves, makes using the filter very smooth.
Great glass. Actually scratch resistant.
Took out my keys and hey no scratches. Thumbs up.
Waterproof.
Filter weighs only .5 ounces. Both the case and filter weight 2.7 ounces.

Overall very pleased with the filter.
Great quality.
I picked up the 52mm version.
Used 2 of my kit lens and no issues. Very smooth to install and remove from lens.
Easy to clean. Should last a very long time.

I prefer to shoot with filters verse going into software and spending extra time to get a similar effect.
Hope this was helpful.

Product sent by supplier was wrong, ordered a 77mm and I received a 82mm, I've had to purchase an additional Step Down ring to convert it as I can't return as it'll take too much time. Other than that, I've played around with the filter already and it's a lot of fun and I'm excited to use it in upcoming projects.

I’ll be honest up front, I ordered this mistaking it for an ND filter, I’ve decided to keep this though as I really like the effect it produces.

I’ve been getting into landscape photography and wanted an Nd filter but ordered this by mistake, after having a play and wanting to eventually push into portrait I decided to give it a try.

The results are surprising good, it adds a nice glow to bright light sources that give the images some warmth.

The filter is presented in a lovely case with rubber wedges inside that hold the filter in place so it doesn’t slip around.

I can see me using this for product photography and portraits and so far have really enjoyed it

Pros
- nice glow
- gives images a warmer feel
- excellent storage case

Cons
- none ( although keep in mind you may need to adjust exposure times slightly due to very minimal tint )
