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.

I love this with the magnetic cap and filter functionality! I haven’t taken it off since I’ve gotten it. I just love using it and I love how the camera looks when it’s not in use and the magnetic cap is on.
I have attached two photos showing the difference with the filter and without the filter there’s a noticeable difference without losing clarity or detail. I think this is a great purchase!!

I have these magnetic caps on 4 of my medium format lenses.
As the title goes, once the cap snaps on, it stays on, but maybe too sticky for their own good as there are times they won’t come off so easily, yet I love that feature so much.
The build quality is perceptively deceiving as they look malleable but they’re pretty darn solid in the hand.
These caps that came alongside an ND filter are truly worth the money.

Very happy with the night shots I’ve taken with this filter. I got the 1/4th and it ads the glow I was looking for!

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.

As someone who is heavy into video production I am extremely familiar with diffusion filters. I have used them on various projects for quite a while now. What makes this filter from K&F Concept so special besides the awesome look is the magnetic filter system. Having recently purchased a few more different magnetic filters this concept has quickly grown on me and I have almost switched all the way over.
The Diffusion filter does exactly what it should do, no more or less. The filter gives tons more character to your digital images from your DSLR. The magic of the filter is that it causes the highlights (especially light sources) to quite literally glow. The effect adds a dreamy look of halation to the highlights, a common look of feature film styles. I have included a screengrab of a music video I shot using the filter.
In the box you get the diffusion filter, an adapter ring and the lens cap. All of these items are magnetic and snap right into each other. You simply screw the adapter ring into your lens thread and then you just snap the diffusion filter on within seconds you have the dreamy look you have been waiting for.

I’ve transitioned to These type of magnet sets for my cameras because it makes switching effortless and easy.
Also the magnets hold tight so I’ve never been worried about them falling off.

Excellent value for money; the black myst effect is very pleasing for certain types of photos; the quarter-tone effect isn't too pronounced and gives a nice effect without exaggeration.

A truly useful lens for my camera, it does exactly what it claims. The image quality is sharp, and it enhances my footage without any unnecessary complications. A solid addition to my gear, especially for those who want dependable results in every shot.

I would like a little more strength when I place the ND filter and the black mist, the two magnetic ones have not fallen but the scare is there
