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.

This Filter is meant to bloom your highlights and take off the digital look and add a cinematic quality to your footage and it does just that. The magnetic design is a great idea if you had all magnet filters which would make it super easy to swap filters. But if your other filters are ring supported I would not purchase for that option. I am able to mount the camera upside down with no words of the magnets failing me because it is very strong.
I have kept this filter on my camera since I got it months ago so that goes to show you how well this is made and enhances my video production. You can stack this filter but only stack with this filter being last to reduce the chances of making the front element heavier where it magnetizes. I have not compared this to bigger brands but base off of the lower price and quality this provides it’s a no-brainer.
I would definitely recommend to beginner's and enthusiast look to get a "cinematic" quality out of their photos and videos.

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'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.

High quality materials

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!

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.

Great filter for portrait and street photography, it adds cinema graphic look to the photos.

I bought this filter to test it out vs the Tiffen brand pro mist and it did not disappoint. Theres a video on YouTube that compares these two filters side by side and the K&F is definitely a competitor. Price is fair which I liked, it came in a nice container as well. In my opinion dont overpay for the Tiffen.
