It's a really well built nd filter. I bought it for video and it seems to be working perfect. There is a slight green tone to it but other than that I highly recommend this product

It's a high quality filter in a range for normal daywork under average terms. If it's too bright the ND 32 is maybe a little too weak so I look for the higher one at K&F...
I got the ND 2 - ND 400 too and on a bright daylight it work as a very solid instrument. Both of them have just a very little influence in color (minimal green), but nothing to struggle with!
The mechanical adjustment is very good, smooth and with a stop so a "X" is not possible, a very gentle solution.
The storage-box is in a higher quality as for the 400-type, very usable and solid, I like it very much!

Great filter for the price. I haven’t seen any “X” not color cast. Works as intended and feels good to have a hard stop from the min to max strength.

Disappointing in that even at its max setting I can’t take exposures of more than a second or two.

But I think I'll need to go higher than 32ND, though it is of excellent quality I can't seem to get a really long exposure with these. may need to go up to 400 to see the differences.

No color cast or X shape in video or photos when stopped down on my X-T3. Its a great value for the money and the step up rings work very well. Its very smooth turning for adjustment

Filter is not wide enough to accommodate even a standard zoom. I have it mounted on a Sony 18-105 f/4 G lens paired with my Sony a6300. In photo mode, all four corners have a very HEAVY vignette. The vignette is visible from 18mm all the way until about 50mm. 18mm isn't even considered wide - angle on an APS-C Camera. The build quality and image quality itself are very good, however, the vignetting renders the filter unusable. Avoid this product if you plan on using it with a lens wider than 50mm.Update: K&F Concepts offered to send a fixed ND 1000 filter plus Step down filters so I am able to use an ND to take photos. I appreciate the help that they offered me so I updated the rating of this product. This 72mm Variable ND filter is very sharp and has no color fringing. If the vignetting issued gets resolved then it would be a near perfect product - especially for the price. Good customer service but subpar product.

It looks very good quality, very sturdy, the only problem is that once you have the filter on, my lens cap couldn’t stay on any more and the lens hood also can’t be added or removed without taking the filter off first

At time of this review I have had the filter for roughly 4 days.Easily my favorite attribute about this filter is the lack of 'X' problems with photos. With many variable neutral density filters you can spin the filter too far and create an 'X' unintentionally. K&F have solved this issue by only allowing the filter to twist to a certain spot so the use will not accidentally ruin any photos. The filter feels very rugged and sturdy. The portion of the filter that does not spin has grooves on it to easily hold on and twist the outer ring. Great product so far.
