Brilliant variable filters ... I used on my Canon 5DMk4 to take video and these filters gave me the proper exposure / frame rate everytime ... I wouldn't hesitate to purchase more for future lenses of different diameter.

I knew as soon as I opened the envelope I had bought a quality item. Inside the gorgeous black outer box is a round acrylic container which flips open at the press of a button. The Filter rests on its foam bed. It looks like quality, it feels like quality.

Anyone that shoots video using a DSLR knows about camera settings and the limitations this creates in brightly lit environments. This can become a bigger problem if, like me, you like to shoot with the aperture wide open on a fast lens. It was almost impossible to do outside scenes on brighter days. To say I’m very pleased is an understatement.

Pros:
High quality, no dreaded X or aberrations and it only cost £36. I expected a lens of this quality to cost much much more.

Cons:
To be honest, there aren’t any. No, I can’t put the lens cap on when the filter is in place, but it’s no big deal to unscrew it and place it back in its case.

I am just an amateur film maker so my word counts for nought among photographers. From a film maker’s point of view, however, this is a great bit of kit to have in your bag and for the money, you can’t go wrong.

If I didn't know the price of this filter, I would have said very expensive. The coatings are very effective. I also like the copper colour ring around the edge of the filter.

Recently started to get in to hobby photography. Seen a you tube video about different filters. I loved the idea of the variable filter. You change just with a turn. When I looked it up, first thought was wow it is a bit pricey.. but it does give you several filter in one and it makes an amazing difference. Tried it out on the weekend. It was grey and horrible weather but with this filter look at my picture, makes the clouds, and the whole scene look vibrant and beautiful. I’m sold on it!

Great for video when you don't want to close down your aperture when your goal is to stay within your desired frame rate (shutter angle).
It's a well made product at an affordable price point and feels like a premium item.
The bottom line: if you're thinking about this vs the more expensive alternatives, you won't be left short with this.

I have purchased a few K&F Concept products recently and this also doesn't fail to delivery. Still early days but very please with it, ticks all the boxes and for a great price!

An ND filter that does what it says on the tin. As soon as you unpack it, you can tell that great value has been placed on high quality. The transport cover has already been made very neatly and ensures safe transport of the filter. The filter itself is really well made. As soon as you screw it on, you can tell that everything feels really good. The metal ring is slightly matted, which ensures a great grip, especially when setting. Setting between ND 2-32 works seamlessly and really smooth. Absolutely jerk-free but also difficult enough that nothing changes so quickly. When setting it yourself, you do not notice any disruptive influences such as the typical cross that was often found with variable ND filters. The value from ND 2 to ND 32 is also perfect for them most long exposures. Especially when it comes to sunsets or the typical smoothing of water, this ND filter is perfect. In addition, the filter is also nano-coated so that water droplets roll off directly and the filter cannot fog up. What was also important for me was that the filter is not that 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 quality that I like very much. Since the filter starts at ND-2, you don't have to copy it even with normal photos and can vary very quickly. After my first tests, I have to say that I don't want to have to miss this filter in my camera bag anymore. In addition, the filter is nano-coated so that water droplets roll off directly and the filter cannot fog up in the first place.

I 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 not have 'x' when used at 8 stops! Doesn't 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!

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

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 premium workmanship of the product. Since this is a variable Nd filter, I can leave it on my lens as the filter doesn't have to be removed to get more light. I had great expectations for this filter while ordering, and its results are better than my expectations. The filter ring is very smooth and does not jerk when recording a video. There weren't any dark spots on the pages in my photos that I've experienced for some other filters, Prime delivery was very quick and the product safely arrived in a day. I would definitely try other products from K&F Concept,
