Good value for money, arrived on time, as advertised and like the slim but sturdy pouch they supply the filter in

I absolutely love this 77mm filter and it fits my Nikon 70-200 f2.8 perfectly. I use reinforcement rings for other lenses like my 85mm f1.4. The ease of use is phenomenal and it glides so effortlessly. I love this filter. I can recommend him to everyone. Push it to the darkest level, open the aperture wide and take a long exposure during the day for amazing results. Enjoy!

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.

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

Works great if you're starting out with long exposure photography, but has a bit of vignetting and color cast

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!

I used it on my 17-55 Canon 2.8 lens for video. It is wonderful! Nice feeling to turn it, perfect case for transport included. Does j not have an "x" when used at 8 stops! Does not affect the picture quality. I have a similar, only more expensive, other brand that doesn't work as well as this one. I am a professional cameraman and I trust this brand!

ND filters are expensive, everyone who has dealt with them was. Here you get a top product for good money.

Bought for a recent trip to Rome. Never came off the lens. excellent build quality and performance. works silky smooth, love it!

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.
