I use the anamorphic lens by Moment and FilmicPro to make movies using my iPhone. The 62mm K&F filter is very important to get that filmic look when I am shooting at 24fps. I have tried cheaper ND filters but they had vignetting and poor image quality. With the K&F filter the clarity is great and the build quality is solid and durable. The included case firmly holds the filter. This ND filter is a great value and much better than the other lesser ND filters I have tried. I have included photos with the same camera settings without any filter, with a cheap filter and with the K&F filter. I also included a photo of the setup I use. This filter pairs perfectly with the moment 62mm filter mount. It is a game changer for anamorphic video especially when filming outside. I could not be happier with the K&F ND filter. It is superb quality and value! I totally recommend it!

The vignette with this filter is a serious issue and I wish that I had read about this issue before purchasing it. You can see the issue in the attached photo.

I shoot with the Fujifillm X-T3 which arguably is the best video camera under $3000. However it lacked the variable ND filters that you would find built in to more professional video camera. I needed some more motion blur and lower my exposure when shooting video and this does it amazingly without any noticeable loss of details and colors. For the price this is a very valuable tool in my arsenal. The build quality is really nice with an all metal construction. The ring itself is smooth and allows for a nice variable exposure change. I really dig this ND filter and I think anyone should take a look at this since the image it produces are pretty clean.

Great picture quality. Has a stop in the ring to keep you from getting in the orientation that causes the cross pattern abberation.

A very good filter. It’s very smooth and has a stopping point. I used this on my sigma art lens for a shoot. No vignetting!

I was pleasantly surprised by this variable filter. I use this with Moment lenses to film on my iPhone. I previously tried out another brand but the distortions made the video unusable. I was skeptical about the K&F Concept filters because the price was so low. But the reviews were good so I gave it a try. The packaging and case was nice and the filter itself felt like a well-engineered product. Everything was higher quality than what I was expecting. Then I tried the filters and my video came out great. The only issue I really notice it when you crank up to the highest setting. But that seems to be the case for just about every variable filter I have seen. If you stay just under that, it is perfect. I even bought a few additional filters for my regular camera. For the price point, you get a really good product. I would definitely recommend this.

Pretty damn good. I’ve shot with it several times over the past week or so. It’s awesome. Great quality filter.
