What I photograph with it is great. The bag that comes with it is also very high quality. From me there is a clear purchase recommendation.

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...

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

Very robust quality glass, the yield is excellent I attach the shooting test of this filter in combination with the gnd8 from the same manufacturer, highly recommended

The filters come in a stable, robust bag and are very good in terms of imaging performance. The glass makes a solid impression and even various beach sand contact (during a hurricane) did not cause them to scratch. Clear purchase decision.

When comparing dUKx footage sets with and without, be aware of quality differences.

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!

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.

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!

Quality filter, there are 5 steps, it is convenient for sunny days, it comes with a leather case with a magnet to close it, the filter is made of glass and not resin, the quality and price are luxury, I have more expensive filters from other brands and they are worse.
