IMO, the only way this could be better is for it to have a darker ND filter setting.

Since I started doing long exposures , my variable ND filter of choice was Vivitar. It's worked great over the years but I was in need of a new filter.Since I also own a K&F Concept tripod, and they've treated me well, I decided to give this filter a try. What could be cooler than an ND filter and a circular polarizer in one?! And I'm glad that I did!This filter works incredibly well. With my old ND filter, I had to stack a separate circular polarizer on top which would lead to vignetting on my widest shots. With the K&F Concept 2-in-1 filter, that no longer appears to be a concern at 18mm. At 10mm, I've noticed a very slight vignetting which is almost unnoticeable. But, it's definitely a huge improvement over filter stacking.While it may require 2 hands, this filter is very easy to adjust. It also feels well built and sturdy.All in all, this filter was well worth the money invested.

I love the fact that one filter has variable ND and Circular polarizer. This filter works really well! The quality of the glass is amazing and i don’t get those unusual flares! It beats carrying two filters! I used to stack ND filters and polarizers and did not work quite well because it created unusual flares. I got a size bigger than my lens size to prevent any vignetting. Very happy with my purchase!

I've always struggled with situations where I wish I could use my variable ND filter with my polarized filter which until now, it was impossible. This filter solves my problem with really good picture quality.

This is my first ND filter, so I can’t tell you if this is quality product or not compare to other brands. This ND filter did the job for outdoor recording, my footage came out amazing with proper camera setting and the right time to film. I never had several friends asked me if I’m happy with the result because they were amaze by it.

It easy to use...fits my Zeiss 16-35mm and my 24-70mm and gives me very nice results....allowing me to dial in the right amount of exposure for the effect i want!
