Great filter
Love it. Easy to use. Must use dots for correct alignment. Moving to the min/max mark will produce the "X" you see in some photos. That is purely user error. I've done it myself. What I love about the variable filter is I can put this filter on my lens on the lowest setting, set up my shot and focus and then twist it to the max setting to take my shot. No need to remove the filter to set up another composition.
Photo: nikon d7100/ sigma 18-250mm
Iso 100
shutter 1/6th sec
f/4.5 (I think)
Nd- highest setting
Rushed to take this shot as I was being eaten alive by black flies. So i messed my aperture up and kept bumping my shutter up instead to get an acceptable exposure. I also had some condensation on my lens when I was screwing on the filter so there is a haze towards the top of the image. Shoulda used f/11+ and a 1 second exposure, but the water still blended nicely.

Very good price / delivery ratio
I already have a few products from K&F Konzept and everything is great again! Works very well and smoothly. The image quality is great and I can finally film more openly in the sun. This filter does exactly what it should, namely darken the picture. I did not notice color errors or poor image quality.

Super useful, excellent product
Very easy to use, looks very good material. I love the result. Playing with the white balance you can get much better result. I have tested with ISO 100 f / 1.8 and 1/125 sec. when the sun does not let see anything in the camera, and this has allowed me to put it totally dark and also in a desired tone.

Nice, bright
This thing is ridiculous! Got it yesterday and took it out today for some waterfall pics in a small stream close by. This was around 5 in the afternoon. Nice, bright, sunny day. I was able to get 20 second shots with no problem and could have taken even longer ones. I did get a few nasty flares on a few of my pics but I think that was my bad as I was shooting towards the sun and it is not on all of my pictures. I'll have to try again and shoot with the sun to my back and see how it does. But for the price there is no reason not to have one for each of your lenses. Very happy with this. And it's nicely constructed of metal and screw in smoothly. 6 Stars!

This filter is able to get stunning pictures at such a great price.
Long exposure. At first I hardly used it, now I'm a huge fan. I shopped around and found the perfect tripod (carbon-fiber Manfrotto, also great). When that arrived, I mentioned to my friend I was planning on getting waterfalls with a slow shutter speed, and he said, "You gotta ND filter, right?" I knew I had a trip up to Letchworth coming up that weekend. That evening I rushed onto Amazon, shopped around, and found this product. Perfect size for my Zeiss 50mm and 35mm!
I didn't really get the chance to mess with this ND filter until I arrived at Letchworth and wow was I blown away! The crisp rolling ring and the crisp shade of black make this such an incredible product. So worth the price! I'm blown away by how it doesn't degrade the quality of my captures my lenses can get.
I love long exposure now. With my lightweight tripod and my filter, I can only grow.
I included a picture of a covered bridge in Cuyahoga Valley National Park taken with this filter. It was a eight second shutter speed.

Vintage Slower Shutter Speed Film Camera
Handy for older manual film camera with max 1000 or 500/ sec shutter speed to meter in sunny daylight, lens wide open. Metering can be adjusted by turning the ND to meet the correct light exposure at a set shutter-speed and choice DOF (f-stop) combination. Wonderful tool for needle metered or LED array camera where you see the progress of exposure as you turn.
Retractable Rubber hood is the best solution to attach a hood.
Lens cap for a 67mm will be 72mm. I will assume 1 size larger.

Possibly to be used for minimal darkening, but for long exposure during daytime crap.
After I needed a new neutral density filter for my DSLR, I decided on this model and was not disappointed. I am an amateur photographer. Professionals may have different needs, but I was not disappointed.

Do what it says on the tin. Well built. Easy to adjust. Has a certain polarizing effect. A must for sunny days. I really don't understand why an "amateur" would spend more than 30 euros on ND filters. The quality from K&F is very good and the price is even more impressive, I recommend this!

Spectacular filter for the price!
I almost gave up on trying to invest in an ND filter because I wasn't ready to spend $200 or more on some waterfall shots. Came across this one and LOVED it. Took it on my trip to Italy, and it provided some phenomenal shots in full daylight. It worked great with both 30-second exposures of waterfalls and also when I just needed it to block out the haze from the rising sun at the top of St. Peter's Basilica. Sure, there might be a shadow around the edges, but the overall quality of the photos that this provides is well worth it.

Surprised with this Filter
Definitely a nice surprise! I expected an average filter for the price point, I am attaching a copy of one of the first 5 photos I took with it in the Smoky Mountains. The first 4 were just figuring out the shutter speed I wanted. Quite pleased, wife happy - can't ask for anything more. Looking forward to many pictures using this 82mm Variable ND Filter with my Tamron 24-70 lens (or a more wide angle when I can afford one) on my Nikon D-500.

FAQs

From 1-5 stops, there will be a slight X cross for lens under 24mm. An X cross will appear at the highest stop and can be removed by rotating the filter ring, which is a normal situation instead of a quality issue.

Tested with Nikon Z 7 and Nikor 14-30mm Sline, dark corners are not obvious for 14mm and no dark corners for 16mm.

As K&F Concept ND2-ND400 filters adjusts the amount of light that can pass through with polarizing glass, a colour cast can't be avoided for all the variable ND filters on the market. However, K&F Concept variable ND filters are made by the best coating technology, which reduces the effect of the polarizing film on image color. *Based on our professional test, the colour cast of K&F Concept ND2-ND400 filters is around 290k while the industry standard is 500k.

A
To avoid dark corners, K&F Concept ND2-ND400 filters are designed in ultra-wide construction so the front side of the ND filter is one size larger than the camera lens. It is recommended to use a lens hood of a larger size.
