absolutely love this 77mm filter and it fits my Nikon 70-200 f2.8 perfectly. I use reinforcement rings for other lenses like my 85mm f1.4. The ease of use is phenomenal and it glides so effortlessly. I love this filter. I can recommend him to everyone. Push it to the darkest level, open the aperture wide and take a long exposure during the day for amazing results. Enjoy!

used it on my 17-55 Canon 2.8 lens for video. It is wonderful! Nice feeling to turn it, perfect case for transport included. Does j not have an "x" when used at 8 stops! Does not affect the picture quality. I have a similar, only more expensive, other brand that doesn't work as well as this one. I am a professional cameraman and I trust this brand!

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.

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.

I use the filter both for filming with the DSLR, as well as for long-term exposure during the day with an open aperture, especially when filming, it is simply beautiful with an open aperture. The ring is easy to turn. However, sound should be recorded externally, because the ring clicks quietly in the intended positions. The packaging is ideal for transport and also withstands the attacks of my 1-year-old daughter. The picture quality looks great. In any case, I could not see any color casts or other disturbances. I am very satisfied with the ND filter.

Brilliant for the price, although you soften it up a bit with these, but still great

ND filters are expensive, everyone who has dealt with them was. Here you get a top product for good money.

The filter looks valuable and the packaging is good. Unfortunately, my copy showed clear vignettes in both the direction of ND32 and ND2, making the filter virtually unusable. In addition, the minimum stop was not clean, so that a clear darkening was already visible at minimum (>ND2), only turned a little further did I actually have ND2. So it went from slightly darkened (>ND2) to bright (ND2) to significantly darkened (ND32). It's a shame, but that's why I sent the filter back. I then did not examine the glass quality more closely.

ordered this filter for my Canon 800d and it works like a charm. The packaging it came in gives you a sense of the premium build quality of the product. Since it is a variable Nd filter I can leave it on my lens as there is no need to remove the filter to get more light. I had high expectations for this filter while ordering and its results are better than my expectations. The filter ring is very smooth and does not stutter when recording a video. There were no dark spots on the sides in my photos which I have experienced for some other filters. Delivery by Prime was very fast and the product arrived safely in one day. I would definitely try other K&F Concept products as the ND filter does the job.

The filter came as described at a good price, the packaging is very valuable. I can't say anything about the quality here because I've only tried it once and the pictures aren't available yet. However, the handling was great.
