Review: Great nd filter - Great price, reliable, and high quality glass
Review: Too much 'X' cross & vignetting - UPDATED - The vignetting and 'X' cross was way too much on my wide angle lenses, I returned this and purchased the K&F NF 3 filter set. NOTE: I have updated this review to 5 stars as This company, who accepted my return with no issues, just contacted me and offer me a full explanation of what caused my issue as well as additional compensation to make me feel better. That, my friends is customer service! BTW, I was so impressed that I declined the offer, they refunded my money for the original purchase and that is all I could ask for.

## 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 77mm lenses. Check your camera's lens thread size (usually beside a "ø" diameter symbol) before ordering. An 82mm lens cap is also required for this 77mm 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.

### ⭐⭐⭐⭐⭐ Great nd filter
*by E***S on August 1, 2026*

Great price, reliable, and high quality glass

### ⭐⭐⭐⭐⭐ Too much 'X' cross & vignetting - UPDATED
*by E***K on December 6, 2024*

The vignetting and 'X' cross was way too much on my wide angle lenses, I returned this and purchased the K&F NF 3 filter set. NOTE: I have updated this review to 5 stars as This company, who accepted my return with no issues, just contacted me and offer me a full explanation of what caused my issue as well as additional compensation to make me feel better.

### ⭐⭐⭐⭐ 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.
