“The marker on the side of ND2 – ND32 is fixed so you can't walk past it and accidentally see a cross on your video.

Delivery - Fast, timely and safe packaging. The filter has its own box, so you can safely go out into the wild for photography. Have you ever tried photographing water in direct sunlight? You pass the waterfall and you want to take a great photo, but due to too much brightness your options are limited - believe this has happened to me several times, but with the K&F Concept ND filter the problem is solved. I'm an amatUKr photographer who loves spending time in nature and I think ND filter is something you need to have in your gear ASAP. Being able to adjust how much the filter should be closed and thus get a darker filter is a great thing. The filter is mounted directly on the lens, simply throw it back (note the size of the lens!). You can still take it, it's not difficult and you get great effects with it! Long exposures without an ND filter are a nightmare and having ND filters in your pocket will be an amazing thing. Another thing I would recommend is the mobile app (there are more - just try it) to calculate the shutter speed with the ND filter. You can find the formula on the web, but we need to use the technology correctly. I can warmly recommend K&F Concept Filter!

It's a must have in your camera bag and at a fraction of the cost of other brands of variable ND filters.

have a Sony A7III with some of the Tamron lenses they recently released, 67mm thread on the dUKx. I first used the ND on a daylight midday shoot and was amazed by the results. The best part is that I can choose the number of stops I need to make the zebras disappear with ease. Ease of movement and robust construction. Only negative is that the sun visors don't fit after turning on the ND. Not a deal breaker but be aware. EDIT: I also took it with me on a trip to Lake Tahoe and it came in really handy for longer exposures and more sky contrast. Awesome and so easy to use!

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.

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
