As a photographer I'm always looking for ways to save weight, then save money. Being a longtime Lee Filters user I was skeptical about changing to a product half the price and always heard bad things about circular variable ND's. Man I was shocked by how good this product is. Really happy and will be buying more.

An ND filter that keeps what it promises. As soon as you unpack it, you notice that great value was placed on high quality. The transport cover is already very neatly worked and thus ensures safe transport of the filter. The filter itself is really well made. As soon as you unscrew it, you can tell that everything feels really good. The metal ring is a bit frosted, which ensures a great grip, especially when adjusting. Adjusting between ND 2-32 works seamlessly and is really smooth. Absolutely jerk-free but also heavy enough that nothing changes so quickly.When adjusting it yourself, you don't notice any disturbing influences such as the typical cross, which was often the case with variable ND filters.The value from ND 2 to ND 32 is also perfect for the most long-term exposures. This ND filter is perfect when it comes to sunsets or the typical straightening of water. In addition, the filter is nano-coated so that water droplets roll off directly and the filter cannot fog up in the first place. Which is still important to me was that the filter is not so thick and heavy. This is where the K&F Concept ND Filter really shines. It is almost as thin and narrow as a normal UV filter. A feature that I like very much. Since the filter starts at ND-2, you wouldn't have to write it off even with normal photos and can vary very quickly. After my first tests, I have to say I wouldn't want to be without this filter in my camera bag anymore.

used it on my 17-55 canon 2.8 lens for video. Its amazing! Nice feeling to rotate it, perfect case for transporting included in the box. Does jnot have ‘x’ when used at 8 stops! Doesnt effect image quality. I have a similar just more expensive different brand variable nd and performs not as good as this one. Im a pro cinematografer and i trust this brand!

Absolutely love this 77mm nd filter it fits perfectly on my nikon 70-200 f2.8. I use stpe up rings for other lenses like my 85mm f1.4. The ease of use is phenomenal and it slides so effortlessly. I love this nd filter I'll recommend it to anyone mslide to the darkest and put your aperture wide open and shoot a long exposure at day time for amazing results. Enjoy!

Good product, good seller, and fast shipping. I would recommend this product to every one that wants a good ND filter for the money

was sceptical about this product with the price but this is a great ND. I haven’t done any ‘proper’ testing but from the footage I’ve shot with it, it’s 10/10. No noticeable colour cast or any vignette. I would recommend!

This is my first square filter! The first thing that struck me was the very elegant and practical packaging - the ring that takes the filter out of the storage box is very clever.

Far exceeds expectations. Quality of packaging matches a much more expensive purchase. The visual quality of the filter is equally top-notch. After using the filter in my filter holder, I can't see any evidence of color cast or filter clarity. Overall, I have nothing but great things to say about this offering. Will definitely look to this manufacturer for future filter purchases.

I am very satisfied with the optical quality of this filter. Especially in comparison (eg with Cokin) it proves that you don't work with a plastic toy. The transitions are smooth and not immediately (frighteningly) noticeable

This is already my 2nd gradient filter from K&F, I still have the GND 0.8 and am very satisfied. Simply unbeatable for this price. I can't see any color distortion.
