52mm Black Diffusion Pro-Mist 1/4 & 1/8 Filter Special Effects Filter Ultra-Clear Multi-layer Coated With Waterproof Scratch-Resistant and Anti-Reflection Nano-Xcel Series

I've used this filter a couple of times for my creative photography and videography in a couple of instances and i can tell you K&F Concept nailed it again.

I can't post images of content i was paid for due to contractual reasons, but this is definitely a professional grade filter.

I noticed no image resolution degradation, no white balance issues, no vignetting or distortion when the filter was on.

It arrived on a rather large protecting case that i discarded right away and it was unwieldy, hard and larger than it needed to be, but i own a K&F filter pouch (shown on pictures, not included with the filter) that i use.

Despite not liking the carrying case, this is a GREAT Black Mist filter, it feels premium on your hands, mounting was smooth, it feels sturdy and while i did NOT test scratch resistance i trust K&F Concept products.

Great value for a premium filter, i would recommend it to anyone who is in the market for one.

When I first found out about this lens filter, I knew I needed it. I've spent so long in editing programs just to get a subpar hazy/soft affect on my photos, but this filter is what I've needed this whole time to streamline my photography workflow. It's the perfect filter for that dreamy film affect!
The top photo is without the filter, the bottom photo was taken just a second later with the filter. It ads a beautiful softness and warmth to the photos!

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

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.

I bought this filter to remove the sharpness and the too digital look that today's cameras have. 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 marked when we frame light sources, creates the halo of light around the main source, whether it is the sun or an artificial light.

Great for giving a vintage and particular touch to your photos / videos

Nice filter. Definitely comes handy in certain situations. Great for sharp lenses especially with no character. This adds some mood to it. It’s nice to have, looks well made and o love that I can apply to a lens and still be able to use the lens cover over the filter when not in use. I use it on my Sony 18-105 f/4 and the 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 what it does.

I start by saying that this filter will remain forever on my Canon 24-70 and that I am satisfied and amazed by the effect it gives to my photographs.
The filter comes in a hard case that already differentiates it from low-end filters: it is comfortable to use and has a non-slip part with different notches for multiple filter sizes. The construction is excellent and can be seen immediately from the layer applied to the surface which is a professional tool.
If you are a photography geek like me, to give an effect similar to diffusion / glow, you have already tried things like petroleum jelly on the lens, stockings pulled on a filter or various films. Here this filter is anything but. It has a sneaky effect and does NOT degrade the image. The edges remain sharp while the colors seem to fade slightly inside the photo, restoring the quality that was had with the use of film: really nice! I bought it for photography in broad daylight, but surely one of its best applications is with lights at night where you can appreciate more this diffusion of color and brightness. Despite being an overused term, this filter lends an organic feel to digital photographic pulp. I would like to point out that it does not have a blatantly and vulgarly widespread effect, but visible without attracting attention. Highly recommended for videos too!

Would 100% recommend

Black Mist filters are designed to give a dreamy look to pictures and especially video by creating a 'glow effect' to the whole picture. The hard edges of the picture will be softened but the contrast of the dark areas will be mostly retained. For the best effect you want to use this filter especially around light sources. A subtle glow will be added around the light spots.

In the box you get the filter and a slick carrying case that can also hold other filters at different sizes. This filter produces some gorgeous shots and it is on par with many other filters that cost more than this one.
The strength of the effect from this 1/8 varies depending on the scene, although it can be quite dramatic in certain situations comparing to those from other 1/4 filters. But with all said and done this particular strength is pretty much in the middle. It is never too much and it is never too little. Great filter.

K&F contacted me to test the new Black Mist filter.
It is a filter designed for videos and to give a "vintage" touch to the final result.
In short: beautiful result even for photography. It is a useful filter for portraits or for landscape or storytelling reportage. You do not lose sharpness and you get a much less "shot" light that also expands in the shaded area.
It is a filter to be used in photography with large apertures and which "tells" an atmosphere.

But let's start from the beginning.
Packaging / handling: In addition to the plastic box, the filter is inserted in a very resistant and protective snap-on case. The filter is screw-type (rightly because it was created for videomakers and in any case up to a diameter of 82). I would have preferred a cardboard box. But the case that you can see in the photo (the round one) is very useful and sturdy. The filter is resistant and fits well to all the lenses to which I have mounted it.

Technical review:
It has no dominant details, so it leaves the colors similar to the photo taken without a filter. Great!
It does not lose light, there is no need to increase the ISO when it is mounted. Great!
The sharpness in the details (and here comes the beauty) remains almost unchanged. You DO NOT lose sharpness in the areas in focus even if I would not use it in ultra-defined landscape photography, but for a storytelling, outdoor or portrait set absolutely yes.
Autofocus is unaffected by the filter, at least not on the Nikon D750 with fixed lenses.

Usage / Effect: it is a filter that gives a “glow” effect to photos, very particular especially for videos and for portraits in harsh light or backlight.
The highlights are dimmed but without becoming dull, moreover the light "enters" the shadows, giving a very soft "glow" effect. Great for portraits or to give a more dreamy atmosphere, it removes clarity from the image in high contrast areas.

In the photos you can see a couple of unfiltered / filtered comparisons, two portrait photos set and what comes to you.

Result in short: it is a filter that you do not think can enter your kit, but when it does it has such a particular result that you would try it in any situation. A must try!
