K&F Concept 67mm Variable ND Lens Filter ND2-ND400 (1-9 Stops) 18 Multi-Layer Coatings Adjustable Neutral Density Ultra Slim Lens Filter for Camera Lens

good product and fast shipping

Amazing product at the best price! Perfectly packed and delivered , highly recommended!

Great product. Very good quality and you can adjust it however you want which is very useful. Also, I would like to point out the amazing service the “K&F Concept” provided me when I faced some problems. I had salt and sand stuck on my filter which I couldn’t clean. I asked the customer service for help and they offered me a replacement of the filter, which I really appreciated!

Good, edges are dark

For the price, this is the best VND. Shifts color slightly but nothing that cannot be fixed in post. Only problem is that it works upto 8.5 stops. Still gives me a 2.8 aperture shutter 50 in UAE’s harsh midday sun. Unlike others who commented, my filter sits properly with the markings on the top on Sigma 24-70 f2.8.

Very very good quality performs very well highly recomended

I use this with my Fuji XT-5 with 18-55 kit lenses.. the camera makes no changes till you reach the nd level of 5+ stops and then images darkens dramatically.. the transition is not well controlled but gets the job done.

Nice gud

El uso de repente hace que se vea como telaraña la imagen

Well, the ND filter simply does its job. It gives me a lot more control over the 16mm f/1.4 lens from Sigma, which is an excellent piece of glass. Since it is a fast, wide angle lens, there can be challenges which are easily dealt with using an ND filter. I did read the comment from a reviewer that mentioned an dark "x mark" across his image. I had to see if I could replicate it with this. I cranked the filter way past what I would have normally set it for, and was able to see the x as well. Neat. It's easily fixed though. Just don't "crank" an ND filter further than is necessary. I have a feeling that most all of them will exhibit the same characteristic, so it's just a matter of operator procedure to see that it doesn't happen. Honestly, I had never noticed it, simply because it was a setting that was never called for, given any of the lighting conditions I was shooting in. I can go to manual settings on my camera, and get a blacked out image, if I push the settings into "deep space", but why would I? Otherwise, the filter shows good edge sharpness, and no detectable distortion, but I'm not terribly picky. It gets rid of what problems I might have had with a high speed, wide angle lens, which is what I bought it for. Nice ND filter, and I'd buy it again.

nice filter

It leaves the purple lines on the edges

Product surpassed expectations. Would buy again.
