After reading some other reviews that said that the magnetic ring wasn’t strong enough to hold the filter I just wanted to try myself. I have no problem with the ND filter falling of the lens. I use this in ND on stage filming artists. The only thing I find strange is that is doesn’t come with a magnetic lens cover, you have to buy this separately.

I have only been experimenting with this lens for a few days but it worked very well at the beach where I wanted to "smooth out" the water on a very brightly lit day. The photos came out well and the filter fit perfectly for me--I had no issues installing it or removing it (it didn't stick in place as some filters can). It is certainly an interesting filter for landscape photographers or those interested in refining their art.

Over all build quality and design is very good but Having vignetting with 24mm lens, Best to use with higher focal length than 24mm

Initially, I did not like the fact that when I was trying to rotate to change stops, the whole body of the filter was rotating, but then I realized that there is a special lock of the filter when you place it on a magnet ring locking body of the filter and allow easy rotation of the adjustment ring.
The overall quality of the filter is superb. Great color and sharpness. No X pattern.

Perfect filter if it had a cap to leave it mounted.

This is a nice filter. It works as expected without a color shift of X-Pattern.
The magnetic attachment is pretty cool. It allows easy changing of filters via a small magnetic ring. I don't currently own any of the other K&F magnetic filters, but I can see the value of the eco-system. I like that i can easily add or remove an ND filter without screwing/unscrewing. The magnet does seems a bit weak, so I'm curious to see if I'll run into any issues of the filter inadvertantly coming off. I'll report back if I have any concerns after road testing it more.

It rotates smoothly. I do wish it had a know like the 1/4 diffusion ND filter does. That was a brilliant design.

It comes in a sturdy clear plastic case.

For a variable ND filter, I'm happy with this.

Serves good for my Sony 16-35 F4. No image degradation as far as I can see even at 16mm

For a dad-photographer who was on a week's trip with my family (of four kids), having this on my lens was just efficient and practical. I could switch from shooting video to taking stills just by taking this off whenever I needed to. Although, I only wished that K&F would sell just the magnetic "mount" - as I wanted to keep another on my other lens. In spite of that, I also got the ND64 just to have that extra one but also ended up using that filter.

The magnetic system is simply easier and quicker to use when adding or removing filters. The glass appears to be high quality, and have really liked what K&F Concept has done with these filters.
