Just getting back into photography mode. So new DSLR camera set-up. Never used ND filters before. Wanted to try them out. This filter does what it intended to do. Being new to ND filters, didn't know what to expect. It is nice build Quality, I did not get quite the effect I was looking for but that was not the filters fault. This is a 2f stop to 5f stop filter. So I bought an other K&F filter that is not a fader ND filter but is a 10f stop filter. the second photo is with just the 10 stop filter. once my adapter gets here (filters are of different sizes, 52MM & 55MM) I will even be able to stack the two together, for up to 15f stops slower. Over all very happy with the K&F filters.
Does what it is suppose to. Does what it is suppose to.

This was a life saver when my HSS died, and had to use a regular speed strobe... I don't see any of the vignetting that others see... If you see it, just turn a little till you don't.
LIFE SAVER!

I bought this filter for my Sony nx80, and it fits perfectly. This is a great option for outdoor shooting either for photo or video. You can easily just twist the filter to change the amount of light going into the lens. great product that makes a difference when shooting on a sunny day. But I did notice that when I zoom in, it struggles focusing the object. It's something that I need to figure out. Other than that I would defenetly buy it again.
 Great Filter for the price!

I have never tried a ND variable filter before, but I'm glad I gave this a shot. I'll be mainly using it for outdoor video. I didn't have to bump up my shutter speed when putting this thing on. Photo example is 1 frame from a video I shot in my backyard with and without the filter at it's maximum with same camera settings. 1080p @60FPS @125 shutter speed.
Love it for video

I bought this adjustable ND filter to use on my Canon EF lenses during my trip to Iceland. It worked beautifully and allowed me to capture some beautiful landscapes!
 Love the optics!

At time of this review I have had the filter for roughly 4 days.
Easily my favorite attribute about this filter is the lack of 'X' problems with photos. With many variable neutral density filters you can spin the filter too far and create an 'X' unintentionally. K&F have solved this issue by only allowing the filter to twist to a certain spot so the use will not accidentally ruin any photos. The filter feels very rugged and sturdy. The portion of the filter that does not spin has grooves on it to easily hold on and twist the outer ring. Great product so far.
No 'X' problem anymore No 'X' problem anymore

I love this filter great for Photo & video.
But at 10mm on my 80D Crop sensor it casts a shadow above.
if I zoom in a bit like 14mm it goes away.

NO X, No Color cast. Great Filter... As Advertised. and Great Build...

I used this to take photos of the moon through a very mild cloud covering using my Kowa TSN-99 spotting scope with an IPhone 15 Pro Max mounted onto the scope. I have attached "with" and "without" photographs to this review. The "without" photograph shows ghosting and is blurry, whereas the with photograph is pretty much perfect.
Outstanding moon pictures thanks to this filter Outstanding moon pictures thanks to this filter

The filter is a little tricky to get on with the lens hood, but if you put the lens hood on, with the filter down inside the hood, then screw on the lens filter, it works, but it's hard to make to work. The lens cap however doesn't fit. The performance of the filter is great, good for video during the day shooting log with my R7. Can't beat the price. I leave it on my lens now all the time. Has a really nice look to it.
Awesome filter for my Sigma 30mm 1.4
