Review: great filter - So great! Easy to use, looks great, fits perfectly and it's wroth every penny. Comes with a case to protect the lens, and differently from other brads it gives a clear look, only gets a lil bit of vignette if you use 0.5 lens

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 49mm lenses. Check your camera's lens thread size (usually beside a "ø" diameter symbol) before ordering. A 52mm lens cap is also required for this 49mm 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.

## Questions & Answers

**Q: What is the difference between the old and new version of this ND filter?**
A: hello,the new version of this ND filter is double-side multilayer blue coating

**Q: At what point will an x spot appear? what is the useable range? how does this compare to your no x model?**
A: If you rotate your ND filter past the ‘Max’ mark on the filter rim, it can cause an x-pattern, so ensure you’re not over-rotating. Variable ND filters also have limited application with wide angle lenses (they can only be used to about the halfway mark of Min and Max markings because the field of view is so broad). For a wide-angle lens, we suggest using fixed ND filters or ND2-32 or ND8-128. You can also try adjusting your focal length and reducing the density (rotating back towards the ‘Min’ mark) until the colour shift disappears.

**Q: If i rotate the density from nd2 to nd400 and have a lens hood connected to the 77mm front threads, will the hood move?**
A: hello, for the 77mm nd filter ,the lens hood  size  should be 82mm
for the 72mm nd filter , the  lens hood  size  should be 77mm.
by the  way, when you use  a nd filter , you better not add  a lend hood ,the  lend hood should move.

**Q: Can i still return it if i opened one of the cloths?**
A: Yes, you may return it; as long as it's in your 30 day window to return it.

### ⭐⭐⭐⭐⭐ great filter
*by G***A on December 3, 2025*

So great! Easy to use, looks great, fits perfectly and it's wroth every penny. Comes with a case to protect the lens, and differently from other brads it gives a clear look, only gets a lil bit of vignette if you use 0.5 lens

### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐ Add green hue, vignetting, but is very affordable
*by A***W on January 24, 2026*

Adds a green hue and has vignetting at the max ND stop. AWB or manually setting WB will fix this, and I don't need the max ND stop, so for me this is OK, but they could be issues for others. Otherwise, works as expected, and is cheap! I bought the 46mm and 37mm versions, happens on both fyi.
