Easy to use and superb optical quality. I bought a larger size than I needed and a step up ring do I just needed to buy one that would cover up to my largest lens.

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 design is nice and sleek. I like the little box pouch it came in, with this magnet type latch. works as promised and theres no issues so far.

Those are seriously underrated !!
Amazing VND ! Better than the tiffen for sure (but that’s not hard to beat - they make terrible filters), and I think might be better than polar pro ?!
The most amazing thing about it is that it seems to have a build in IR cut !! IR cut filters cost more than this VND !
As a blackmagic camera user - I had very bad IR pollution with no DIY VND or any strong ND, I didn’t see any with this one, and tried using a IR cut in front to see if there is any difference and couldn’t see any on the pocket !

I shoot with the Fujifillm X-T3 which arguably is the best video camera under A$5000. 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.

I was debating between the K&F Concept ND filter and some other brands. BUT, I am really happy that I went with these because the build quality, picture quality, and performance are out of this world! Great ND Filter for videographers with hard spots.

I now use more my camera without worrying about the reflection or bright spots I love that is easy to install and I can change to less filter to higher. The package is a great addition to protect the ND I definitely would love that.

Still I have to try more the filter with the Pandemic situation is not possible to test this on other scenarios or more often still holding my final review.

I purchased this because I didn't want to spend hundreds on other options out there and this one works very well. A little green cast but overall not too bad. It has saved me when I film outside and want to get the best looking background compression in the sun. Comes with a nice case and its built very well. Love the indicators that tell you how many stops you are adding. Would purchase again.

After reading tons of reviews and comparisons to more expensive ND filters, I settled on this one. I was not disappointed! It performs exactly as advertised. There's no dreaded "X" at higher settings. It is a high quality item and a welcome addition to my Fuji kit. I bought it to fit the largest thread size I use (Canon EF 70-200) and use step rings to use on smaller lenses. It works great!

Product: 58mm Variable ND2-ND32

Description: The rim of the filter is made out of what I'd assume is aluminum, coated matte black, (which has a nice weight to it, and has hard stops at ND2 & ND32). The rim itself is actually fairly nice. It's easy to put on, and easy to take off due to the wide ridged design around the base of the filter. The high index optical glass is indeed nano coated to protect against water/oils from fingerprints, rain, & etc. Which are easily removed without struggle in my testing with a clean micro fiber cloth (not included). The glass itself has a slight yellow tint to it (which you can see from the photo comparison), which can also easily be corrected through your cameras auto white balance, or lightroom. The filter also doesn't loose to much detail if adjusted properly which is nice as you will see from the photos, and their description in the next section.

Photos: The first four photos of the product were taken without any filters. Though the next two of the black & red mouse pad were to show detail comparisons. These two photos were taken about 1-2ft away, but are cropped to show detail. Which were slighty adjusted to be as equal as possible.
Without the filter: F4.0 1/15s. ISO 400
ND32: F4.0 1s ISO 400

The next 6 photos of the flowers next to the bird bath were taken without adjusting any settings to show the darkness of the filter (F5.6 1/320s ISO 100), in this order: No Filter, ND2 1st, 2nd, 3rd, 4th, & ND32 5th stop.

Overall: The produce works well, and is well made! I would highly recommend picking one of these up, along with a circular polarizer. Though only notable things I found with the product is that it has a slight yellow tint of the filter, the front thread size of the filter in bigger then 58mm, and the top of the filter very slightly wiggles. Otherwise it gets a solid A from me!

Extra: I used a 49mm-58mm step up ring for the filter to fit my Canon 50mm F/1.8

Camera/Settings: Shot on a Canon Rebel SL3, with custom white balance settings set to +/-0,+/-0 for raw color quality.
