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!

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!

Great filters from K&F. I lean towards using the 1/8th. Over the 1/4 but everyone is different. Not sure why the case has to be that big though. Its noticiable in your camera bag/Nanuk case.

If you’re looking for some good quality black diffusion filters, it’s hard to beat K&F Concepts at this price point. The quality of materials, fit and finish. And overall clarity and effects of this product, provides a fantastic way to add a great tool to your photography toolbox.

At the time of me writing this, many people have already described these filters abilities and what you can get out of them, so I’m not going to get into any of that. I will however agree with the abilities of these two lenses and say that I’ve found them to achieve exactly what I hoped for and with a clarity and quality you’d expect.

Overall, this product is made very well, it fits perfect on my lens and does a fantastic job at what it’s intended to do. If you would like to add the abilities of black diffusion filters to your bag of tricks, this is a great choice that I highly recommend for this price point.

I have included some pictures and video to help show the quality of the product. I hope you found this information to be helpful in your decision.

I think people are sleeping on these K&F diffusion filters. I have been using these for some time and I have been really impressed with them. In fact I see little difference between these and the Tiffen Black Pro Mist filters that cost a heck of a lot more. I mean think about it...these are diffusion filters. They aren't supposed to be perfect. They are meant to give your image a softer look by diffusing the light a bit. They provide some nice bloom to the highlights as well.

The 1/8 strength filter is a great all around filter that I use for a lot of my shoots. I only go to the 1/4 strength one when I am looking for that really dreamy look.

I've been using a smaller-diameter K&F Concept Black Diffusion 1/4 with my 35mm prime, now I've got this larger 77mm-diameter set for my Sigma 17-50mm f/2.8. I live near the water and I really enjoy the way these expand highlights from the opposite shore.

These black diffusion filters are fantastic for giving a softer appearance to photos and portraits. I use them with a mirrorless camera and love experimenting with the 1/4 and 1/8 filters for different effects. They fit my lens perfectly and they feel like they're high quality. The cases they come with are nice as well. I recommend them for sure.

I haven't yet tried this with video, but with images this really softens edges and it is like viewing the subject through a thin mist and these vastly reduce and eliminate glare, which is the whole point of a diffusion filter. If you are shooting in bright sun, at the beach or in a garden, and are having issues with flare and glare, then these are your go-to filters.
