I use a Fujifilm X-T3 camera and have this to match my 55-200mm zoom lens. The mounting ring attaches easily to the lens and I'm a big fan of the magnetic attachment for this filter. There are many different brands of diffusion filters. I have used Tiffen brand filters in the past and have always been happy with them, but when I came across the K&F filters I was dying to try them.

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

This magnet system does not disappoint. Replacing the filters is very easy with the magnetic attachment system. The lens cap for the filter system has been criticized by some but I think it works very well. It actually reminds me of some lens caps on my Pentax system, so I felt very comfortable with them.

As for the quality of the diffusion - excellent! I really enjoy the softer look this diffusion delivers without being too heavy.

However, one thing surprised me a bit. I expected to be able to install this filter system and then still use my tulip shaped lens hood, but I can't do that with this K&F attached to my lens. To be honest I wouldn't be surprised if that really is the Fujifilm system's fault as I've found the lens hoods to be difficult to attach compared to other camera systems I've used in the past. That said, I intend to purchase more K&F brand ND filters to take full advantage of this magnetic attachment system. It's a winner in my book.

use this filter on my Fujifilm X-S10. I can't fault it. The short thread is perfect so it attaches to my lens with no problem. It's a thin filter so it doesn't stretch the lens much at all. The polarizing feature works exactly as it should. The filter offers great value for money over more expensive brands. The only thing to note is that it comes in a large box, that is, a generic box that fits filters of all sizes. Since my filter is a 52mm filter, it is relatively small, so the box seems unnecessarily large.

Perfect companion to my Fujifilm X100V and Hogue Lens Cover. The fact that it's waterproof is a plus; This filter is an excellent addition due to its WATERPROOF HIGH QUALITY UV FILTER. Happy to find it at Amazon.com Arnold

bought a FujiFilm camera. It's difficult to buy lenses. I bought an adapter to use a Nikon lens. It has an aperture ring, so I shoot in A mode. Of course, it can also be used in S mode. I don't use M mode. It is very helpful when it is difficult to buy real lenses. Thanks very much.

I have this 57mm Sigma lens for my Fujifilm X-T30 and I am super happy with the results. The effect is subtle, but that's exactly what I wanted to achieve with the pen.

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.

Fantastic piece of kit that allows you to use your Nikon G lenses on your Fujifilm. You have to go into your Fujifilm settings and set it to take photos without a lens, then it works fine. The aperture is set on the smallest lenses and the aperture ring only changes it by 5 stops. So if you have an F4 lens, you can't go to F16, for example. It has a bit of weight, but it is of excellent build quality. I've used it with a 50mm Nikon lens and a 70-200mm Nikon lens and there is absolutely no movement when everything is connected. It fits perfectly. The focus peaking works well when using the adapter and the focus is spot on. (see photos taken in a dimly lit room) Sharpness is maintained throughout. Since the Fuji is an APS-C and my lenses were made for full frame there is a crop of 1.5 which makes my 50mm 75mm on the Fujifilm and when I use the 70-200mm it gives me due to the crop a focal length of 105 - 300 mm without loss of quality. If you have Nikon glass and a Fujifilm X camera, this is definitely a win-win-win-win for you and saves you money. Yes, it can't be autofocus, but that's a small price to pay, manual focus with peaking is a lot more fun anyway. I definitely recommend this adapter 100%.
