I normally use 1/8 strength diffusion filters which just lowers the contrast a bit and adds some bloom to the highlights. I was shooting a project where I wanted a bit more of a dreamy look to it so I wanted to try this as it should be just a bit strong than a 1/8th strength but not make my footage look too dreamy looking. It did indeed do just that. I noticed so real color cast with this filter. I got stronger bloom in the highlights and just gave my footage a softer more film like look.

Just be sure you want a stronger effect that a 1/4 filter can give you. If it's too strong K&F does make a 1/8 strength black diffusion filter that is excellent.

The magnetic system works very well. I wish all filters used this type of easy to use quick release system.

As someone who is heavy into video production I am extremely familiar with diffusion filters. I have used them on various projects for quite a while now. What makes this filter from K&F Concept so special besides the awesome look is the magnetic filter system. Having recently purchased a few more different magnetic filters this concept has quickly grown on me and I have almost switched all the way over.

The Diffusion filter does exactly what it should do, no more or less. The filter gives tons more character to your digital images from your DSLR. The magic of the filter is that it causes the highlights (especially light sources) to quite literally glow. The effect adds a dreamy look of halation to the highlights, a common look of feature film styles. I have included a screengrab of a music video I shot using 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 right into each other. You simply screw the adapter ring into your lens thread and then you just snap the diffusion filter on within seconds you have the dreamy look you have been waiting for.

Nice filter. Certainly useful in certain situations. Ideal for sharp lenses, especially without character. That brings some mood into the game. It's nice to have, looks well made and I love that I can put it on a lens and still use the lens cover over the filter when not in use. I use it on my Sony 18-105 f/4 and Sigma 18-35 f/1.8 and am quite happy with the result. In my images, the last image is the one without the filter, hopefully you can get an idea of ​​what it does.

I bought this filter to get rid of the sharpness and overly digital look of today's cameras. The quality of this Black Pro Mist from KeF is excellent, the result is identical to the more expensive filters from Nisi.

The effect it gives is mainly apparent when we frame light sources that create a halo around the main source, be it the sun or an artificial light.

Great for adding a vintage and special touch to your photos/videos

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.

It is a filter designed for videos and to give a "vintage" touch to the final result. In short: wonderful result also for photography. This is a useful filter for reportage or portrait or landscape narration. You don't lose sharpness and you get much less "pulled" light that also expands in the shadowed area. It is a filter to be used in photography with large apertures and which "tells" an atmosphere. Technical review: It has no dominant details, so it leaves the colors similar to the photo taken without filter. Great ! It doesn't make light, you don't need to increase the Iso when you mount it. Great ! The sharpness in the details (and here is the beauty) remains almost unchanged. You don't lose sharpness in focus areas although I wouldn't use it in ultrafine landscape photography but for a storybook, outdoors or portrait together absolutely you. Autofocus is not affected by the filter, at least not on the Nikon D750 with fixed lenses. Use/Effect: This is a filter that gives a glowing effect to photos, especially special for videos and hard-light or backlit portraits. The reflections are lowered but without becoming dull, moreover the light "penetrates" into the shadows, giving a very soft "glow" effect. Ideal for portraiture or to give a more dreamy atmosphere, eliminates image clarity in high contrast areas. In the photos you can see some comparisons without filter / with filter, two portrait photos together and what comes to you. Bottom Line: This is a filter you don't think you could fit into your kit, but when it comes in, it has such a distinctive result that you try it in any situation. Absolutely to try!

Favoring shooting to post-processing, I tried this filter with the only lighting of an electric garland and the rendering was good, the light from the garland is diffuse and softer. Can't wait to use it for night video when the restrictions are lifted.

You can see from the images, it makes your image more cinematic, it adds a bit of softness to your images. This filter paired with my Sony A7S III and my F4 24-105mm gives me a whole new perspective! So happy with this purchase!

Great little filter made specifically for Cinematic effect.
I'm a professional photographer. I had written a rather lengthy 5 star review, but it was rejected for reasons I am not aware of. I recommend this filter if you are looking to soften the visual impact of your photos and video.
