In my opinion, a nice ND filter. Excellent value for money. With 3 stops you are good for most situations. I have attached an application before and after ND. No obvious color change to my eyes other than darkening the image. However, it is common to find color casts that are unique to most brands. This can be done in the mail if it is not a lot. For that price point, this ND isn't an idea, especially on a budget. It looks well done, the glass and packaging are decent enough.

Very well designed ND filter, nicely packaged with efficient storage method as shown in the photo. Is screwed onto the lens with high quality threads (ie no loosening or scratching noises). Very happy with ND results and have already bought a second lens (46mm) for another lens.

I tested this filter for 2 weeks on a Voigtländer MFT 10.5mm f / 0.95 Nokton. I don't use the filter to take long exposures, but to block enough light to be able to work with a large (or even full) aperture. , i.e. f / 0.95 or f / 1.2, during the day and outdoors. The filter is very well made. With 21mm effective focal length on my lens, that doesn't matter, but it's good to know if you're using a wider angle. Treatment level, it seems to be pretty effective. I had practically no flare and the filter didn't change the colors or the sharpness. That's a very good point. I attach 2 photos taken with this filter to the lens. The packaging is completely correct and classic. There is nothing to report on this page. The same goes for shipping. I haven't noticed anything negative (so far) and I'm very satisfied with this filter.

I bought this ND for the first time, I am satisfied with the quality. I have no experience with other filter manufacturers, for me ND filters are quite sufficient. Can't say anything negative, do what they're supposed to do. A clear buy recommendation from me.

I ordered this lens filter for my husband. He has a Cannon DSLR camera and this filter is a perfect match for his camera. Thanks to this filter, he was able to take better photos during the day. It's a very fine filter, but it's not fragile. It's well done and works as expected. I recommend this lens filter for beginners and professionals.

As a photographer, I really try to make sure that I only use reliable equipment. K&F has done a great job of being a reliable low-cost camera equipment company. I have some of their other pieces of equipment and continue to be impressed with their dedication to superior build quality and attention to detail in their products. I found the filter screwed directly onto my lens with no problems and was also able to remove it without any problems. Unfortunately I couldn't take long exposure as I don't live near a waterfall and when I got this filter the weather really didn't cooperate with me. However, I held the filter to the lens without screwing it onto the lens, so that I could see the difference between the picture with the filter and the other. In this type of test, you can see a properly exposed image and a slightly cloudy image clearly by showing only the "hot spots" of light in the photo. I took a few photos with the filter installed and found there was no edge vignetting and since the glass is high quality I didn't notice any ghosts either. Overall, this is a very good option for a budget ND lens filter. that there is no edge vignetting and since the glass is of high quality, I did not notice any ghosts either.

I use it on a Fujifilm telephoto lens mainly for video. Image quality is very good without aberration, relatively easy to screw/remove, hard protective case. Recommended for anyone looking for a good quality fixed ND filter.

With all of these new product releases that K&F has released lately, it is obvious that they have decided to improve their game in terms of the real quality of their products. This ND filter is a prime example of this. This is a glass filter and the coating they use seems to help with the flare up quite well. I find that it doesn't attract dust particles like some of my other ND filters. This is a fine filter with small ridges on the opposite sides so it is very easy to attach to my lenses. More importantly, I see very few colors with this filter which terrifies me given the price. Whatever K&F has been doing lately, I hope they continue to do so.

“The K&F Concept ND 8 filter is a handy item to have in your kit, especially if you are looking for a well-built filter at a reasonable price. The filter has a gradation factor of 0.9 or three stops, which allows you to use slower shutter speeds during the day or in bright conditions. The filter has 18 coating layers. The aluminum frame is light and very thin, and I had no problem screwing on a lens. The manufacturer also states that the filter is both waterproof and scratch-resistant. I used the 58mm filter on a 50mm lens and, as expected, didn't see any vignetting. The filter is also supplied in a single case with a grooved rubber insert, which enables K&F to Keep filters of different sizes in a single case. The rubber insert helps hold the filter in place in the housing. K&F Concept seems to offer high quality products at affordable prices in the market. Highly recommended !"

I can finally get these beautiful daytime shots! The 3 stops of this lens give me the great moody images I've been trying to achieve. The lens doesn't discolor my photos, so I'm easily able to color in without issue. Fits my Canon M50 - 55mm lens. Snaps on and off easily. This lens saves me tons of money where I would need to buy different Canon lenses. I love this add-on and it works great!
