bought this lens filter because I was looking for a filter no thicker than 3mm that would fit in a new Haoge lens hood (which cannot take thick filters) for my X100V to protect the lens and the camera to make weatherproof. If you don't know anything about the new X100V, you need a filter that is weatherproof. After some searching for a 3mm thick filter I found this filter from K&F Concepts on Amazon. I was skeptical that it would only cost £5.99 and there have been some complaints of a color cast. However, I thought I'd give it up for the price. The box it arrived in isn't the best, but it did its job and the filter arrived unmarked. I held it over a white surface and I could actually see a slight shade of brown. However, I don't see any color cast in the pictures. If you hold the filter up to the light you can see a purple reflection. I have tried to show this in the pictures but there is some fading. It looks very similar to the anti-reflective coating you have on glasses - I don't mind that. Overall I'm amazed, it's actually a really good filter with good spread and no obvious ghosting — I shot in the sun yesterday and it worked really well. I've bought far more expensive filters in the past that weren't as good. Recommended — consider buying a second one as a spare!

For Fuji x100v, its easy to install and can be flipped to accommodate a WCL/TCL or a lens hood like in the photo. Will have to actually test it for street photography if its really water and dust resistant.

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.

Sits well on Fuji x100v. I tried it at night, the diffusion is good and the contrast is also preserved.

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 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.

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%.
