As described, the filter came at a good price, the packaging is very valuable. I can't say anything about the quality here, because I tried it out first and the pictures are not yet available. However, the handling was great.

I have an ND 400 that I use for waterfalls etc but do not always want to block that much light so was looking for something a little faster Maybe an ND16. I have had variable filters in the past but have never been happy the dreaded Xs on the screen when you rotate or uneven color cast across the screen.I saw the K&F advertised claiming that you did not get any of thease issues so thought I would try and they are great, very even light reduction across the frame and no Xs.I have the 77mm filter it is really well made there are stops on the rotation so it it easy to tell where the limits are, the frame itself is slightly larger that the 77mm so no chance of vignetting in the corners, the slight disadvantage of this is I can not seem to fit the filter with my hood in place but not a huge deal.Highly recommended.

Works great if starting out with long exposure photography but it does have a little vignetting and color cast

Bought this for a recent trip to Rome. Never came off the lens. terrific build quality and performance. worked silky smooth, love it!

I like this filter ideal for photo and video. But at 10mm on my 80D crop sensor, it casts a shadow above. if I zoom in a bit like 14mm, it goes away. NO X, no color cast. Excellent filter... As advertised. and nice build...

It's a must-have item in your camera bag and for a fraction of the cost of other brands of variable ND filters. So far I've tested it with multiple lenses and 3 different cameras using step down rings in low light and full daylight, low ND2 down to DN32 and so far I haven't seen no X pattern. A huge problem with many variable ND filters, even the most expensive ones. Color cast is also insignificant but like ALL inferior ND filters there will be color cast, hell even a $500 will have some sort of color cast, again at a fraction of the cost to have a barely noticeable color cast, or at least one that cannot be easily corrected in LR Nowadays, I shoot with the Sony mirrorless system and every lens I shoot with on my full frame camera has a thread less than 77mm and vignetting is no longer an issue at any filter range and at any what focal length of the lens and i have been shooting the thing a LOT with my sony. Above are some of the photos I took with the filter, including my Canon 5D series and my Sony A7R series. The first 3 are from my Canon and the second 3 are my Sony lens and I've been shooting the thing A LOT with my Sony.

I love this filter! I have it on a 24-105 lens which I pretty much started using exclusively except for a few other lenses here and there. I used to shoot with a Sony FS5 all the time, and its ND filters were about that level. The first screenshot is somewhat color graded, and the other screenshot is ungraded and is from a different camera. I don't think you should compare the two. The important thing for me is to show the versatility you get with your images.
