I feel this is a very nice black mist camera filter for my DSLR. It is made of high quality optical glass with multiple layers of ultra-thin, nanometer coatings and ultra-light materials. The frame is very light and thin compared to some of the other filters I have. This filter is a 1/4 diffusion/mist and the changes from a normal, non-filtered lens, are minimal. The same filter is available in lesser and greater strengths. But, I thought 1/4 was a good place to start experimenting and for general use.

The price for this filter is very good considering you are getting a high-quality, multi-coated glass filter. In my different experimental shots, I think this filter has a lot of potential for portraits and still-life. I'm also wanting to try it out on some more macro shots. I would certainly recommend this camera filter for anyone still shooting with a DSLR and not their phone. ;-)

I have this on 57mm Sigma lens for my Fujifilm X-T30 and I’m super happy with the results. The effect is subtle but that’s exactly what I wanted out of the filler.

In every way this K&F Black Diffusion 1/4 filter is a wonderful filter. Well-made, nicely machined, clear and perfect glass, thin and light, etc, etc. You'll get a very good filter for your money.

The question really is how good is the diffusion effect, especially in the center of the frame where a face is likely to be placed. My tests on some newly budded red bud flowers revealed that the diffusion quality is subtle and excellent from edge to edge. The included photograph is a 100% crop, to capture the quality in the center of the frame. I hope the reproduction on k&f conceept is good enough to sell you on the quality, too.

This is a fine product and easy to recommend.

I've collected a set of mist and black mist filters, having found that I like the ability to adjust the strength of the filter. I ordered 1/4 to fill in the gap between "obvious" 1/2 and very subtle 1/8. This one specifically is a nice quality filter (no significant degradation to the image beyond what's expected) with some nice features (strong knurling on the rim, smudge resistant). There are definitely higher quality glass filters available from the big name brands, but this one does a good job of providing that "soft aesthetic" feel for neon or nostalgia type photography.

My 135mm and 40mm Sigma Art lenses are extremely sharp. Some would say clinically sharp, maybe too sharp for portraits. My personal experience has been that’s not always the case, but I sometimes find myself wishing I could dial them back slightly. This K&F Concept Black Diffusion 1/4 filter does just that, almost like magic.

The effect is subtly-different from applying a similar effect in software. I like that the effect with the filter on the lens is noticeable, but without being too obvious. It’s an excellent compromise that seems to work well for me. Deciding precisely when to use this filter will be an ongoing learning experience that I’m looking forward to.

One thing worth noting is that the effect when on the 135mm lens is not exactly the same as when on the 40mm lens. That might be one reason for the different strength options.

Physically, there’s a lot to like. Construction is solid, the fit is precise and the coating is doing its job. A solid five stars for function, quality and value at the current price.

I use to make my living, in San Francisco, shooting photography and creating art. So, I tend to be very demanding of my equipment. But those demands are tempered by reason.

This black diffusion filter, with very smooth threads and solid construction, by its design nature, alters the image your sensor, and glass, would normally make. And that's good. Today's camera's tend to be super sharp and they create crispy images.

Sometimes, to get the proper feel that you're going for, you want to knock down that sharpness, and specular highlights, a bit. That's where this filter comes in.

It does a great job of almost imperceptibly taking the edge off.

I can see myself using this filter a lot for night shots and for video shooting.

5 stars. One heck of a good price for a filter that performs very well.

Not going to lie, I look like an idiot buying this filter -- and you likely will too. I spent hours watching youtube videos to find the sharpest lenses possible on a budget, only to spend more money to make that lens less sharp. However, I'm a sucker for trends, including the popularity of film photography and the accompanying halation. The filter adds a nice element to night urban photography, especially the bright lights. It's a look that -- as far as I know -- can't be created in digital editing. I've bought a few other cheaper black mist style filters for my point & shoot cameras, but this is the first quality filter I picked up for my "real" camera. I went with K&F because I've always been happy with their quality/cost balance. This filter is no exception. The diffusion is pleasant and consistent across the image. The filter is thin, and it screws on to my step-up ring easily. It also comes with a nice case. Overall I will enjoy adding this to my tool bag.

If you want to know what shooting with this filter looks like and you wear glasses, just let your glasses get really dirty with drywall dust. Every becomes softer and less detailed. If that the look you are after, this filter provides it in spades. It's a well made filter and doesn't cause any optical issues (apart from the intentional softening). No color shifts or added flares. With the 82mm version I saw no noticeable vignetting either. The knurling is well done as well. I'm impressed by the quality of this filter and will be looking at other K&F filters in the future.

This ¼ black diffusion filter from K&F is a very high quality optical filter that provides a subtle but noticeable amount of softening to your photos which renders skin tones with a beautiful softness that doesn't look fake. Highlights have a soft glow/bloom and the overall contrast is slightly reduced.

Unfortunately there is no industry standard on exactly how much diffusion a ⅛, ¼, ½ filter should give the image so each manufacturer decides for himself how much diffusion to add to each filter in their line. I like how much diffusion K&F have put on this filter as opposed to other manufacturers whose ¼ diffusion filters apply too much diffusion.

Another indicator of quality is the plastic boxes K&F decided to provide with their filters. They are superior to other companies' boxes and a pleasure to use. I have two different styles of boxes from K&F and they are both outstanding.

A long time ago I bought a Super VHS camcorder, and first thing, recorded my parents. I plugged it in to the TV and played it back. My mother said "That's no good." I asked why. Her response was, "The picture is too clear. Who wants to see themselves that clearly?"
Zoom ahead around 40 years and I have a Nikon full frame DSLR. Take a picture of someone from across the room, and you can see every pore. That's really not necessary.
Enter the diffusion lens.
This one is built beautifully. The glass is almost invisible, and the ring is sturdy and has ridges for easy gripping. And the storage case is nice, too.
It's a 1.4 diffusion filter, so the effect is subtle. But it is there, and it works.
Great filter at a good price.
