Overall, I am satisfied with this K&F model, which dims the light sources at night and creates a pleasant atmosphere during the day. I use it with an Xpro-1 which makes a combo with an analog rendering for a digital camera.

Really nice quality filter, comparable to more expensive brands. Has that black pro mist look. Softens things and gives lights a bit of glow. The he 1/4 does enough but id be curious to play with the stronger versions too.

I was undecided if I should choose this product or another from a more emblazoned brand. After trying it, I feel very satisfied with the optical and constructive quality.

I have the K&F magnetic system on all of my lenses, and got several of the matching ND and CPL filters in addition to the black mist one here. They're so convenient, easily stackable and the connection is strong enough that I don't have to fear that one of them could fall off. The black mist effect here is very minor, and only really noticeable with plenty of backlighting. Many cheaper filters often have a color cast, but I haven't noticed that with the K&F ones at all.

The only downside is that on my Sony lenses at least the magnetic caps that are included are really hard to pull off when you have the lens hood on the lens (either forwards or backwards). Some grippy element at the front of the cap would've helped with that. I might 3d print some holder and glue that on there to fix it. Since the caps aren't really the main reason to use a magnetic filter system though I'm still giving 5 stars, they would've been a nice bonus if they worked well but they're not really critical to the product.

I have watched different films noticing the use of diffusers. I really did a lot of comparing black matt filters.
This one is perfect. I get the softening without it being noticeable.
This is really a high quality filter. I am very happy with it.

I use a Fujifilm X-T3 camera and got this to go with my 55 - 200mm zoom lens. The mounting ring attaches to the lens without issue and I am a big fan of the magnetic attachment for this filter. There are many different brands of diffusion filters out there. I have used Tiffen brand filters in the past and always been happy with them but when I came across the K&F filters I definitely wanted to give them a try.

I have used K&F products in the past and have been particularly happy with their lens adapter system (I used to shoot with Pentax cameras and lenses and their superb lens adapter has allowed me to use my old Pentax lenses with my Fujifilm camera.

This magnetic system does not disappoint. Swapping filters is super easy with the magnetic attachment system. The lens cap for the filter system has been criticized by some but I find it to work very well. It actually reminds me of some of the lens caps from my Pentax system so I felt very comfortable with it.

As for the quality of the diffusion - excellent! I really enjoy the softer look that this diffusion supplies without it bein too heavy-handed.

I was a bit surprised by one thing however. I expected to be able to install this filter system and then still utilize my tulip-shaped lens hood but I cannot do that when this K&F is attached to my lens. To be honest, I wouldn't be surprised if this is really the fault of the Fujifilm system as I have found their lens hoods difficult to attach compared to other camera systems I have used in the past. That said, I intend to get some more K&F brand ND filters to take full advantage of this magnetic attachment system. It's a winner in my book.

The lens is extremely well-made and the effects that this filter is capable of providing are superb. Excellent construction with precision threads, as well as magnetic instant on/off capability. The NANO multicoating is superb and produces NO artifacts, focus issues, or other issues.

Diffusion filters are used for a number of purposes, not the least of which is for softening skin contrast and creating a "dreamy" effect for portraits and general subjects where a softened contrast is desired.

This 67mm set is a widely used size by many lenses. For me, it is the right size for the majority of my Tamron Lenses, as well as the Sony 85mm f/1.8, SIgma 16mm f/1.4 APS-C, and my Canon 100mm f/2.8L Macro lens. That makes this single filter set a superb value at the already great price on Amazon.

This particular filter model provides 1/4 diffusion that creates a softer, cinematic effect and is outstanding for use in both still photography and video as well. This K&F version uses a unique magnetic adapter that is screwed into the front of the lens and allows for a 1-second attachment of the Diffusion filter for easy use and removal. On/Off instantly.
That makes it incredibly easy to use a camera with or without filters and not have to screw them in or out repeatedly. Awesome innovation!

As a YouTube video-producing influencer and Vlogger, this filter has been fantastic for spur-of-the-moment shots and videos when I see a scene or shot that would greatly benefit from some softening...especially of people for live action or portraits when shooting outdoors in bright light or sun. Shadows are not affected and reflections are somewhat softened. Perfect!

I own a number of K&F filters of different types including UV, ND, Polarizers, and Diffusers. I have come to strongly trust the company's products without hesitation. This particular filter set is a superb value at the price as compared to much more expensive similar filters like those from B+W and Hoya, while providing virtually equivalent performance. Awesome!

For me, this filter is unequivocally a Strong FIVE STAR winner, and gets my honest and VERY hearty recommendation! SImply superb!

Happy shooting!

I haven't used any magnetic mount filters before. It's really nice to have that. I didn't realize how convenient it would be not to have to screw and unscrew filters every time I want to make a change.

The diffusion effect of this lens is easy to notice if you're looking for it, but subtle enough that it doesn't call attention to itself. I was concerned that it might be too much at first, but I like the results. I didn't notice any color cast either. Very nice filter. Does the job well.

I took some fantastic pictures of my grandkids with this K+F 1/4 (67mm) Diffusion filter. Ok, they are my grandkids and incredibly beautiful and photogenic, but this filter really made the pictures pop. It softened their skin and actually revealed more detail. I use a Nikon 750 with a Nikon 85mm 1.8 lens. Normally, I use a B+W F-Pro filter, which is really bright. Most of the pictures I shot with the K+F diffusion filter on top of the B+W filter. It is incredibly to attach the K+F filter. You just screw in the ring and pop in the filter. The latter attaches magnetically, but it's a pretty firm attachment. The filter comes with a lens cover that is also magnetically attached, but not so firmly. I noticed it tends to detach when the camera is jostled a bit in my camera bag. That's my only reservation about this filter. I also took off the B+W filter and used the K+F as the only filter on the camera. It works fine, but I prefer using both: I like the effect and I am also incredibly lazy. The good news is that even with two filters there was no vignetting.

The black piece you see in the photo is a lens cap. The transparent piece, that is under that, serves as a filter of sorts. The cap under that is more of a free pass through attachment designed to stick to either the filter or the lens cap depending on what your goal is.

Basically it's all magnets, so it was really easy to set this up. I just screwed in the base, then the filter snapped on no problem, then the lens cap too snapped on without any issue.

The quality of this set is great. The look of it is awesome too. I shook my camera a bit and the cap did not fall off. Seems to be a great alternative to the locking mechanism that comes with normal caps.

Overall, I'm really happy with this set.
