49mm Variable ND2-ND400 (9 Stop) Filter - Waterproof Scratch Resistant Nano-Xcel Series
SKU: KF01.1458
I bought this filter to reduce the amount of light entering through the camera lens and to improve the overall look of outdoor video. The filter lets me control overexposure and it works very well. The filter attaches easily to my camera lens. The filter also come in a protective plastic case and a cleaning cloth which is a nice touch. I’ve come to expect good things from the K&F Concept product range and this is no exception.

You can feel some vignette, in this filter it is from half to max. Everything else, like the picture quality, sharpness, fits the lense etc, is really good. It is'nt bad for the value of this amount money!

I was afraid there would be problems of being a variable ND with strange effects and no problems. Neither in the corners nor on the ND400, the truth is that it comes as a pleasant surprise for its price. It may have a little green tint, but with a correction of nothing in Premiere I solved it, between 5 and 10 points in the hues tab towards magenta and that's it. Highly recommended, it just takes a stop like the ND2 and ND32 models I usually use.

Very useful with a Sony RX10IV to fight against rays of light that could spoil photos and videos. Small problem the adjustment is fluid, we would have liked a step adjustment. Another problem is that the orange lever prevents the original sun visor from being fitted. However, you have to choose between ten filters and one multifilter and these two small disadvantages. This brand is always a guarantee of good quality.

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.
