The product arrived on time. Regarding the filter, it has a smooth shape with an included gear. I used it with a Samsung S23 ultra mobile and the results were excellent in photography. For video recording, it requires multiple settings to be adjusted.

This is a great filter for video, which is why I bought it. But I was surprised how useful it is for still photography. I used this filter to make a 25 second exposure of a Falcon Heavy rocket launch from a Florida beach.

Picked it up for a Christmas deal and I'm so happy I got this! No quality issue whatsoever. I've used K&F Polarizing Filter and ND (fixed) before and they keep up the quality as always! Used it on my 70-300mm and 35mm and I did not see any X mark at the center which is a very common problem people have. Glad i purchased this Variable Filter. Would highly recommend for a 30+ mm lens (did not try on wide angle lens so Not sure about the X-mark).

The K&F Concept 9 stop Variable Neutral density filter is a well made,well machined and all glass filter that works great for special effects and high speed sync applications! Nicely packaged with a very sturdy carrying case and quality lens cleaning cloth included! Highly recommended!
