## Description

desertcart.com : K&F CONCEPT 55mm Variable ND Lens Filter ND2-ND400 (1-9 Stops) 18 Multi-Layer Coatings Adjustable Neutral Density Ultra Slim Lens Filter for Camera Lens (K-Series) : Electronics

Review: It's a very nice ND filter, at a very reasonable price - Well, the ND filter simply does its job. It gives me a lot more control over the 16mm f/1.4 lens from Sigma, which is an excellent piece of glass. Since it is a fast, wide angle lens, there can be challenges which are easily dealt with using an ND filter. I did read the comment from a reviewer that mentioned an dark "x mark" across his image. I had to see if I could replicate it with this. I cranked the filter way past what I would have normally set it for, and was able to see the x as well. Neat. It's easily fixed though. Just don't "crank" an ND filter further than is necessary. I have a feeling that most all of them will exhibit the same characteristic, so it's just a matter of operator procedure to see that it doesn't happen. Honestly, I had never noticed it, simply because it was a setting that was never called for, given any of the lighting conditions I was shooting in. I can go to manual settings on my camera, and get a blacked out image, if I push the settings into "deep space", but why would I? Otherwise, the filter shows good edge sharpness, and no detectable distortion, but I'm not terribly picky. It gets rid of what problems I might have had with a high speed, wide angle lens, which is what I bought it for. Nice ND filter, and I'd buy it again.
Review: Great Lens Filter ! - This K&F Concept Variable ND lens filter is great, I have already got 2 other K&F Concept filters from recent years, which are also very good and i like very mcuh ! It has "True colour" and maitains the sharpness of th!e image The filter has excellent build quality, and it has a solid metal frame. It has a premium feel to it and precise in use. It also seems to have great performance, much better than cheaper other-brand filters. It is easy to attach to the lens, very durable, and i think it is a very good "value for money" filter

## Features

- Import Optical Glass: Crafted from premium AGC optical glass with an astonishing 18 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: High 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 certain lenses and focal lengths.)
- Glare-Free Surfac: 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 55mm lenses. Check your camera's lens thread size (usually beside a "ø" diameter symbol) before ordering. A 58mm lens cap is also required for this 55mm variable ND filter.
- K&F CONCEPT is the world's No.1 brand in terms of lens filter online sales volume among camera-accessory-focused brands. Source: Euromonitor, 2024 data.

### ⭐⭐⭐⭐ Not a bad filter for the price
*by A***R on June 12, 2023*

This is not a bad filter for the price. I took it out for a trial run doing some waterfall shots this past weekend (you can see the results attached). My overall impressions: - The picture quality was pretty good, but not always tack sharp. - It does suffer from the dreaded black X at the MAX ND setting, but no issues on the lower settings. - It was nice to be able to adjust the ND setting on the fly rather than having to swap out filters. In fact, I frequently found myself adjusting it to the MIN setting to check composition and then moving back towards MAX to take the shot. - The build quality seems good and turning the filter felt smooth and fluid. - No hard stops at MAX or MIN settings, so you have to pay attention there. - The indicator dots don't tell you what ND setting you are on, so you need to keep track. - The filter is larger on the incoming end, so the lens cap from your lens will not fit. - I notice some lens flare with the ND filter when the sun is near the viewing angle that don't show up with just the lens. Since my lens shade does not fit due to the filter end being larger, I had to manually shade the lens to make the flare go away. Overall, pretty decent for a variable ND filter. I probably wouldn't use it for professional-quality pictures, but it works for someone just wanting to try an ND filter and not wanting to have to lug around a whole set of filters on a shoot.
