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

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.

Great filter for portrait and street photography, it adds cinema graphic look to the photos.

excellent purchase I resell because I took a greater perspective and with the adapter rings it makes me a vignette effect therefore I resell
