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

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!

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

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.

The item I received seemed like it was damage. It didnt work as it is supposed to. I may have received a defective unit and had to return it. Otherwise, great quality.

Very very good quality performs very well highly recomended

Nice gud

Good filter for the price they ask. Using mostly for videos.

I’m not satisfied with the qualityIt creates a huge vignette and also X effect
