K&F Concept stands for quality. I already had their other filters in the kit, albeit quite old and with several years of service behind me. Due to an upcoming photo tour of mine, I have decided on something new and have always relied on it.

Overall, the best I've ever tried. The glass does not produce any distortion, the bezel is solid, light and easy to turn thanks to the orange lever, which is particularly helpful when looking through the viewfinder. Easy to transport thanks to the inside lined pocket to protect the filter from scratches. Highly recommended for those who want to take the essentials with them.

KF products have always been excellent value for money, but these last generations have made an incredible leap in quality. I've been using a predecessor of this filter for years to record video outdoors. This one survived. Good workmanship, splendid presentation in these artificial leather bags that now bring perfect results. The genius lies in the orange control (the seal color of the brand), which makes it easy for us to change the intensity of the ND at any time.

All of the reviewers say the feel of this filter is top notch, but some seem disappointed with the functionality. Maybe I'm just lucky, but the finish and precision are spot on. I bought two different sizes and both are great quality and well aligned polarizers (the elements that make it up at night) which means there are no "cross shadow" (XS) issues. Well that's a lie! At some point there will always be an XS, but for me it was just before the 8th (last) aperture when used with a wide angle lens (16mm APSC). This means that almost the entire range can be used, everything you could want with a variable ND filter.

I bought the K&F Concept Variable ND Filter Neutral Density ND2-ND400 (9 apertures) with rotating ring to be able to use a fast ND with different densities. The packaging is very well made, solid and space-saving packaging. The glass filter is light and the density increase / decrease ring is liquid. It does not have a limit switch block.

K&F has delivered again, good value for money. I was looking for a good quality variable ND filter for my lenses and this one does the job. I bought the largest size. Got a nice tote bag. Image quality is great.

Very nice filter to use .. no cross pattern in the filter adjustment. But it needs a hard stop to see what number of stop your at ..
