have an ND 400 that I use for waterfalls etc but do not always want to block that much light so was looking for something a little faster Maybe an ND16.I have had variable filters in the past but have never been happy the dreaded Xs on the screen when you rotate or uneven colour cast across the screen.I saw the K&F advertised claiming that you did not get any of thease issues so thought I would try and they are great, very even light reduction across the frame and no Xs.I have the 77mm filter it is really well made there are stops on the rotation so it it easy to tell where the limits are, the frame itself is slightly larger that the 77mm so no chance of vignetting in the corners, the slight disadvantage of this is I can not seem to fit the filter with my hood in place but not a huge deal.Highly recommended.

Absolutely amazing filters and a great price for glass, no color cast that I can see on any of my support images.

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

For auto rigshots I needed a quality filter at a good price, this would be worth buying at a much higher price! It comes beautifully packaged with a high quality holder for the filter, all made from non-animal products! But none of this matters if it doesn't work, but it does! High quality glass with no tolerable impact on my A7R IV's picture quality. If you need a great ND, this is it!

Good quality filters, very few color changes that can easily be corrected in post-processing. The filters stack with blanking plates at each end so easy to carry in camera bag. Easy to clean like some other brands.

Very good for the price top. The processing is also in the upper range. I will buy more filters from the company.

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 find this filter ideal for photo and video. But at 10mm on my 80D Crop captUKr it casts a shadow over it. When I zoom a pUK like 14mm it disappears. NO X, no coulUKr dominant. Excellent filter... As advertised. and nice build...

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.

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!
