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.

I really like the magnetic features of this set of black diffusion filter and lens cap because it makes it so easy to apply to your lens! It was my first time using a black diffusion filter and I have to say it creates such an interesting effect by diffusing the light and increasing the contrast, it really gives it a dreamlike appearance that I did not think would be possible.

As I said earlier as well, I really like the quality of the lens cap; it is made from a nice high quality durable metal and has a strong magnet which makes for easy application and removal.

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.

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 have the threaded version of this filter from K&F Concept and I have been very happy with the quality of it. I use it regularly to give a subtle softening effect to my images. This new magnetic version is awesome! The magnetic attachment is very strong and it makes it so quick and easy to install or remove the filter and lens cap. Construction quality is excellent; K&F filters are very much in the same league as Tiffen filters. Highly recommended!

I see that K&F has started to produce a range of different filters (ND, polarizers, and diffusion) using this magnetic system and I would definitely be interested in adding more to my collection because it's a terrific system. It would work especially well for the 10-stop ND filter because that's the kind of filter you have to keep screwing on and off (because you can't see through it to focus), so being able to snap it on and off would make it SO much easier to use.

Magnetic Filter Attachment, quick and easy to attach or remove from the camera lens.
THe 1/4 Black Mist filter is fantastic and definitely one of my favorites. The Filter comes with 3 items

1) The Filter Ring that threads on to the lens end
2) The Magnetic filter
3) Magnetic Filter Lens Cap.

Common Question(s):
Can you use the canon lens cap with the Magnetic ring installed (YES)
Can you use the Canon lens cap with the magnetic Filter in place (YES)
Can you use the Lens Cap with the magnetic base without the filter magnetically attached (YES)

Overall, really good quality lens and it is a breeze to install. The Magnetism is strong and the lens cap does not fall off nor does the filter. It has just the right amount of magnetism to keep everything in place.
Very Good Lens and Concept for mounting it to the camera.

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!

I'm a big fan of the magnetic filter kits - this is actually my second one from K&F Concept. The magnets are strong enough to provide secure hold, but are still easy to change without fumbling or fear of dropping. p

These diffusion filters create nice pretty effects in my test shots. I love how they look with warm light, but they create some really fun and cool effects with colorful studio-type lighting as well. I really am happy with this set, and I would recommend it.

This is my initial review for the K&F Concept Magnetic Black Soft Diffusion, and I'll continue updating it as I am using it.

I am so excited to have this K&F Concept Diffusion. I received it this evening and I am in love. I have ordered similar diffuser from a different brand before from B&H and have been disappointed with it, but this one is a whole different story. I love the magnetic feature, it's so intuitive and stupid easy to use. It is true to the picture, maybe even prettier! It's very high quality and it looks exactly like advertised. I love the details, I am always trying to find great deals like this one. I find it very well priced for the quality that it offers, everything about it is screaming premium. It feels very well made, durable and easy to use. I really enjoy the design and functionality. At my age I am always searching for products and items that can make my life easier and better in whatever way. This product has improved my quality of life, I just keep recommending it to friends and family, I will defiantly do another order soon. I am extremely satisfied with it and I do recommend it 100 percent. Definitely a great experience, no complaints whatsoever. All around great product and worth every penny!

It is a “magical” filter for portraits. It softens skin tones and imperfections.
I wish I had known about it years ago.
Absolutely love it. Highly recommend.
