Well made and adds a very subtle change to your photos and video that make them feel more real. Adds a light smoothness and maintains sharpness well.
Great product sold in with a solid protective hard case.

Finally a filter that gives softness to my images without neglecting the details. It also corrects small imperfections on close-ups without detracting from image quality.

I really wasn't sure of what to expect from this filter. I mean, I know what it should have done technically but I have been fooled before with poor quality results and not knowing this brand I was prepared to be let down but I certainly have not been. This filter provides a beautifully softening effect that does not so much outright blur but rather seems to maintain a decent focus while creating a very soft hint of haze. It is very delicate and is a really nice tool to have in a portrait photographer's arsenal. It also has a nice effect on candle and sharp points of lights, creating a softened hue or aura around the light source. It looks a little "dreamy", if that helps to paint the picture.

I used this filter with my primary Nikon portrait lens and I intend to continue shooting with it to learn more about it but to this point, it has been a rather exciting discovery.

I will say that, although secure enough, I do find that this filter does not fit my lense threads as precisely as I am more accustom to. Something seems off but they are not binding, so I will leave well enough alone.

I am very impressed with this filter and think it fairly priced.

Definitely recommended.

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

As most K&F products, the build quality of this filter is quite nice. The threads are smooth, filter ring is powder coated and then optics... well, hard to say they're clear or anything since they're a diffusion/soft filter, but the picture quality is still quite good. More on that later.

The filter comes in a circular filter case that is one of the neatest filter cases I've seen! If they don't sell those as products yet, they honestly could! There are raised partial circles that allow you to place all sized filters in the case, unlike most with a foam cutout (which, admittedly offers more padding). It would be nice for the filter case to have a small sticker on it to indicate what is basically on the box--"NANO series 52mm MRC Black Diffusion 1/4" in my case. In fact the outer box has that listed a few different times, including twice on the sticker label... one on the case would be even better.

The optics look like a clear glass with a bunch of small grey dirt specks. That is the intended design. The effect it creates is a soft diffuse glow; a bloom effect. The contrast is lowered when using this black diffusion filter and overall it looks like a similar effect to a soft filter. The sharpness at the point of focus isn't too affected though, so it can still be used in portraiture as well as in other creative photography. Light sources will bloom when looking through this filter. I find the 1/4 strength to still be quite useful while the 1/2 an 1 may be more niche.

I got this to use with my Fuji xf 35mmf1.4 (55mm thread) I love the vintage look I can achieve with it. Think smoky barroom, portraits behind a candle, any photo where you might want a little extra glow from the lights. I have a much more expensive 72mm pro mist filter, but this one gives me just the look I want when combined with the magic of the xf 35 1.4. Recommended

I bought this 72MM filter supplied with the Sigma 18-35 and it is now indispensable for my video productions. It gives an analog effect that makes the images softer, the action around the lights is perfect and not annoying, moreover the production quality is high. It has a double thread to be able to overlap multiple filters and is equipped with a rigid case, for safe transport, with an anti-slip triangle inside (therefore usable with different filter sizes). At the current price it is a must.

Very good!

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!

I ordered this for my husband and he loves this filter. It has taken some steps out of his editing process. He likes this filter, because it does so much during photo shoots that he doesn’t have to waste time fixing small imperfections during editing. He says he noticed a big difference in the quality of his photos pre editing. The filter is thin and fits well on his camera. The quality of this filter isn’t bad. It seems to be holding up well and not showing signs of wear and tear. Great product!
