Delivery - Fast, punctual and safe packaging. The filter has its own box, in which you can safely go out into nature to take pictures. Have you ever tried photographing water in direct sunlight? Passing the waterfall and you want to take an amazing photo, but due to too much brightness your options are limited - believe this has happened to me many times, but with the K&F Concept ND filter the problem is solved. I'm an amateur photographer who loves spending time in nature and I think ND Filter is something you need to have in your gear as soon as possible. The ability to set how much you want to close the filter and thus get a darker filter is a great thing. The filter is mounted directly on the lens, just reject it (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 ND filters 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's more - just try) to calculate shutter speed using the ND filter. You can find the formula on the internet, but we have to use the technology correctly. I highly recommend K&F Concept filters! and having ND filters in your pocket will be an amazing thing.

Excellent value for money, does not affect image quality in any way, thoroughly tested produces no vignetting or flare or ghosting. Mounted on a 24-70 and a 70-200 really essential for creative shots but especially valid on the video side. It allows you to work on open apertures on sunny days while keeping 1/50 S as the shutter. Feeling of absolute solidity! All-metal structure and solid and precise ferrule in the transition from one ND to another! perfect filter

It's a great option for outdoor shooting, whether photo or video. You can easily twist the filter to change the amount of light entering the lens and it's much easier than having to constantly change filters of different strength or using a 4x4" filter like a Cokin filter. there is no vignetting or "X" pattern that can appear in other models. It's very easy to use, even for the beginner and it's a good thing to have when you want to travel lighter and plan to shoot outdoors.

The marking on the side of ND2 - ND32 is fixed so that you cannot exceed them and accidentally get a cross on your video. Notice no difference in quality when comparing two footage sets with and without. Keeping one of these in your camera bag is a must if you're shooting video and will also help if you're into photography and want to do long exposures.

Some of the best filters I've used! I was sent these filters to test and review, but I will never review a product on which I cannot give an unbiased and honest opinion. I have personally tried this filter and found it to be of very good quality and on par with some of the more expensive brands. I would buy this!

I shoot with the Fujifillm X-T3 which is arguably the best video camera under $3000. However, it lacked the variable ND filters you'd find built into a more professional video camera. I needed more motion blur and lower my exposure when shooting video and this amazingly does it without any noticeable loss of detail and color. For the price, it's a very valuable tool in my arsenal. The build quality is really nice with an all metal construction. The ring itself is smooth and allows for good variable exposure change. I really like this ND filter and think everyone should give it a look as the image it produces is pretty clean.

I purchased this adjustable ND filter to use on my Canon EF lenses on my trip. It worked like a charm and allowed me to capture some beautiful landscapes!

At the time of this review, I've had the filter for about 4 days. My favorite attribute about this filter is easily the lack of “X” issues with photos. With many variable ND filters, you can rotate the filter too far and create an inadvertent "X". K&F has solved this problem by only allowing the filter to twist in a certain place so that use does not accidentally ruin the photos. The filter is very robust and robust. The part of the filter that does not rotate has grooves to easily hold and twist the outer ring. Great product so far.

I was really worried I'd see an X in my footage when using this ND filter as other people have complained about this but I can confirm that there are absolutely no issues with the filter. I love the fact that is has a hard stop. It's so easy to screw it onto the lens and take it off. I'd definitely recommend it to anyone!
