This is a great variable nd filter from K&f concept. Its easy to install, easy to use, effectively reduces light coming into the lens, and has clear markings so you know where you have it set.
The functionality is perfect and this is living on my S5M2x now for all of our outdoor work.
Really great value for what you're getting. My local camera shop had similar items but they were charging significantly more. I'm very happy with the build quality and glass clarity. Really great product.
It comes with a carry case!! this is such a nice touch and makes transportation so much easier when you don't have to worry about your filters getting scratched.

Excellent quality filter! The ultra-low reflectivity really makes a difference—images stay sharp with no noticeable color shift, even at higher ND levels. The adjustment ring is smooth and precise, giving me full control from ND2 to ND400. It’s perfect for both photography and video, especially when shooting outdoors or near water. Build quality feels premium, and it comes well-packaged for protection. A fantastic value for the performance—highly recommend!

K&F is my go to when looking for quality filters and they have models at just about every price point but their Nano-X line is at the top of their series. This VND covers a full 9 stops which helps with your outdoor shots (cloudy to full sun) or when you are looking to improve the motion blur of your video. Build quality is right there with other filters in this price range and there are no worries regarding X cross or vignetting with this filter series. If you are looking for a high quality VND filter this one is one to consider.

I really like the quality of K&F. I have another VND from them as well ones from Neewer and Freewell. So comparing this one to those, there are a lot of things that I like and just a couple that I am not too crazy about.
I love the build quality. The movement is smooth. The handle makes it really easy to do a micro-adjustment. The case is one of those nice PU leather ones with the ribbon. The hydrophobic coating works great. I dripped a few drops on it to test and they just roll right off. I touched it with my finger and couldn't tell where I touched it.
As to the quality of the photos, I don't notice any color cast, although I do shoot with auto white balance, and also don't usually need to take the filter all the way to 9 stops. I used this on my 35mm 1.8.
The only things I don't like as well is that this is a beefy filter. I prefer to have a filter case with me because I have some pro mist filters and some creative filters. This one is just thicker than all the others. So I have to watch how I stow it in my bag. The advantage with a filter that is a little bulkier like this is that it is easier to thread on and off. Also, I know the description says it is stepless. This is fine. But I would prefer a slight tactile response to each step. And it would have been nice if there were a hard stop at each end of the range.
Overall those are minor nitpicks and are mostly just a preference. This is an extremely well-engineered filter and is the nicest one that I own. I have really enjoyed shooting with it.

THE PERFECT TOOL FOR CREATIVE LONG EXPOSURES
I was recently shooting the exterior of a historic Gold Rush era Court House here in Northern California, but there were constantly people walking through the frame. To solve this, I needed to use a long exposure, which is where a good ND filter is essential.

An excellent ND filter once attached easily changes from 1-9 stops with accurate density. As always with K&F Concept their upscale filters always come in a quality leather protective case. Set then forget for that correctly exposed movie shot.

Like all of the K&F filters I have- this is exceptional. I am a hobbyist photographer- not a professional- but I have thousands invested in my gear. I don't have the capability to truly test the accuracy of the stops- but to have one filter that I can use for up to 9 full stops is great for landscape photography here in the Sunshine state where I live- or anywhere you're needing to accommodate for changing bright lighting conditions. I only have one lens that this filter fits- which is a 35MM 1.8- so it's great if I want to go wide open in the sun and use the filter to step it down while maintaining the bokeh I am looking for. A very nice lens filter- machined well and easy on/off on my lens. Buy with confidence- a good filter at a reasonable price.
