I've had variable filters before, but I've never been happy with the dreaded Xs on the screen when spinning or the uneven color cast across the screen, and they's great, very even light reduction across the frame and no Xs. I have the 77mm filter, it is very well made, 77mm so no vignetting in the corners, the small disadvantage with it is that I can not fit the filter with my hood, but no big deal. We recommend.

I was skeptical of this product with the price, but this is a great ND. I have not done any "real" tests, but based on the footage I took with it, it is 10/10. No noticeable color cut or vignette. I will recommend!

I shoot with the Fujifillm X-T3 which is arguably the best video camera under $3000. However, it lacked the variable ND filters you'd find built into a more professional video camera. I needed more motion blur and lower my exposure when shooting video and this amazingly does it without any noticeable loss of detail and color. For the price, it's a very valuable tool in my arsenal. The build quality is really nice with an all metal construction. The ring itself is smooth and allows for good variable exposure change. I really like this ND filter and think everyone should give it a look as the image it produces is pretty clean.

I purchased this adjustable ND filter to use on my Canon EF lenses on my trip. It worked like a charm and allowed me to capture some beautiful landscapes!

The filter comes in a really stylish packaging with a magnetic lock and has a small plastic box for transport. The filter can easily be turned on and off the lens. The gray filter has different settings, at min it takes about half an f-stop down in brightness, estimated at maximum setting 3- 4 full f-stops. The best way to see the effect in backlight or strong contrasts in the subject, I look forward to testing the filter in the midday sun in the summer.

I bought the filters to expand my collection. I have now found the right ones. Delivered very quickly and came in a very stylish packaging with magnetic closure. The filter itself was packed in a high quality plastic box. Using adapter rings, the filter was quickly attached and did a great job. Easy to use and great workmanship, I can recommend it to anyone looking for a filter.

Este filtro lo uso con un lente 56mm f1.4 para fotografía de retrato, sesiones, etc. Y funciona perfectamente, no pierde calidad en las imágenes. Así puedo tomar fotos aunque haya mucha iluminación sin pasar de 1/250s

As a photographer, I am always looking for ways to save weight, and then save money. As a long-time Lee Filters user, I was skeptical about switching to half the price of a product and always heard bad things about circular variable NDs. Man I was shocked at how good this product is. Really happy and will buy more.

At the time of this review, I've had the filter for about 4 days. My favorite attribute about this filter is easily the lack of “X” issues with photos. With many variable ND filters, you can rotate the filter too far and create an inadvertent "X". K&F has solved this problem by only allowing the filter to twist in a certain place so that use does not accidentally ruin the photos. The filter is very robust and sturdy. The part of the filter that does not rotate has grooves to easily hold and twist the outer ring. Great product so far.

I ordered this filter for my Canon 800d and it works like a charm. The packaging it came in gives you an idea of the product's first-class design. Since this is a variable Nd filter, I can leave it on my lens as the filter does not have to be removed to get more light. I had high expectations for this filter while ordering, and the results are better than my expectations. The filter ring is very smooth and does not jerk when recording video. There were no dark spots on the pages of my photos that I have experienced for any other filters, the Prime delivery was very fast and the product arrived safely in one day. I would definitely try other K&F Concept products as the ND filter meets the requirement.
