Review: Good quality items for reasonable price. - As an intermediate photographer thats most of the time on a budget Ive found this company to have some good quality stuff for a fraction of the price most big name brands sell them for. Ive so far oreded a few items from K&F CONCEPT and I got to say their product is really good so far. The lens filter is just as described and I love the matt finish of the material used. The material used feels high quality and feels really durable all for a good reasonable price! Its not too heavy very light weight and was able to install on to my lens with no issues. Now there is plenty more positive things to say but, I just have a couple of things that I found personly disappointing/annoying when using the lens filter. Cons: 1. The lense filter sits properly but you loose the ability to use your lens cap. Id have to remove the filter and place lens cap where as other filters I was able to keep on my lens and still place the cap on. 2. The dial to choose how much of the ND filters to use just continues to spin I feel like when shooting having to continuously look where im setting it too will become tedious. Id suggest having stoppers when reached max or min and to possibly have groves to feel what setting im on like slight click in between each "setting". But thats just me being annoying and picky lol. Aside from the "negative" opinions I will be buying more products from this brand. As it is I am currently waiting on a lense cap with UV filter for one of my other lens and I cant wait to receive it.
Review: Excellent Quality ND Filter for Professional Results - This ND filter is a fantastic addition to my photography gear! Made from high-quality AGC optical glass with 8 multi-layer coatings, it really reduces reflections and glare, resulting in crystal-clear images. The 1-9 stop light adjustment is incredibly versatile, perfect for everything from bright daylight shots to more controlled, low-light scenes. The 360-degree rotation offers precise control over the light reduction, although, at the highest stops, I did notice a faint cross-pattern ("X" effect), which is typical for adjustable ND filters on some lenses. The filter itself is sleek and slim, just 7.4mm thick, and the CNC-patterned edge provides great grip, making it super easy to attach or adjust quickly. I love the anti-glare finish, which minimizes stray reflections, especially in challenging lighting. One thing to note: you’ll need a 55mm lens cap for this 52mm filter, but that’s easy to work around. Overall, it’s an impressive ND filter with outstanding performance and durability. Highly recommend it to anyone looking to improve their outdoor and landscape photography!

## Features

- 【Import Optical Glass】Crafted from premium AGC optical glass with 8 multi-layer coatings, this ND filter reduces reflections and glare, ensuring superior image quality.
- 【Versatile Light Control】With 1 to 9 stops of adjustable light reduction and 360-degree rotation for precise dimming settings, this filter is perfect for diverse scenarios. (Note: Max stops may cause a cross-pattern effect, commonly known as an "X black cross." This phenomenon is natural and temporary, occurring due to the adjustable ND filter's interaction with specific lenses and focal lengths.
- 【Glare-Free Surface】Treated with an oxidized sandblasting process, this filter prevents unwanted stray light and minimizes unnecessary reflections on the metal surface.
- 【Slim and Secure】At a mere 7.4mm thickness, the CNC-patterned design ensures enhanced friction while rotating, making it easy to attach/detach lenses and accessories anytime, anywhere.
- 【Compatibility Note】This ND filter suits all 77mm lenses. Check your camera's lens thread size (usually beside a "ø" diameter symbol) before ordering. Additionally, a 82mm lens cap is required for this 77mm variable ND filter.
