Highly versatile filter with exceptional clarity and durability. A must-have for photographers and videographers seeking precise exposure control.

feel like all adjustable filters should come with a putter like the one that comes with this variable ND filter. I have a few K&F concept ND filters already, but this one is by far my favorite. As usual, the optical quality of the filter is excellent - there's no color shift, and the tint is even and consistent throughout the frame with no hotspots. The entire range provides a very good spread of stops from 1.5 through 1000. There's a hard stop at both ends of the putter range to stop you from going beyond the stops. As a result there's no "X" or aberrant pattern. Just crisp, even, density. Filter threaded onto my lens smoothly and effortlessly. No binding. The putter is obviously a major selling point, at least for me. Comes in a nice little storage case that offers plenty of protection for the filter while you're not using it. Great filter through and through. RECOMMENDED>

The products from K&F are simply always insane. The quality is convincing across the board. I can easily adjust the aperture stops with the filter and that with an absolute top imaging performance. What more could you want. The filter is definitely worth the money!

Photo examples I have just unfortunately not, but such filters are used, for example, to represent the water blurred / soft, if the exposure time is too long and thus the image would be too bright. With all filters you have to be careful not to screw them too tight. If it is very cold or extremely warm, then you sometimes have problems to remove the filters. That will also be the case with this one.

Easy to use and fit, will be using with my samsung s24 ultra.

I think something like this is good. A variable filter. It's enough for me as a hobby photographer.

Good quality Very nice product

really like this brand - the nd filters are just easy to work with and get the job done - very reasonably priced. Nothing fancy and they work

The filter does what it's supposed to and looks extremely classy. The leather case is also very classy.

What does a photographer do when they want to create a look for a photo session and that look requires multiple shooting angles.... but you only have one ND filter for one of your 82mm lenses?

... get another ND filter, of course.

Yes yes... I know, it was a cheesy way to start (but a very real problem we ran into a few months ago).

The fact is, I honestly don't know what's happened to K&F in the last few years, but they've gone from being "Oh.... Another filter manufacturer" to a "Wow... that's a fantastic result!!! Who makes this filter? '

This filter is NOT an exception to the above.

ND filters are often a double edged sword for photographers.... They work and they do what you want them to do.... sort of.

They tend to add color shift to your images, distortion if you have cheap glass, and they can often move your camera to the point where you have to manually adjust the shutter control... which leaves you taking photos after trial and error.

Also, when you use an ND filter, especially for very long exposures, you have to fight the light, so to speak. As the light of the day changes, so do your exposures.... and while you do a lot of trial and error, a 5 minute exposure at noon won't produce the same result at 5pm, so it's not like you can "set it and forget it" so to speak.

If you then add the word "variable" to the equation, things tend to get even weirder. When you adjust the ND, you often experience strange streaking, sudden fluctuations in exposure as you adjust the ring, AND that doesn't even take into account that so many ND filters have very loose adjustment rings that (I kid you not) can sometimes change their setting when a strong breeze blows.

This filter... IMPRESSIVE... I can honestly say that I have none of the above problems. There IS still a slight color shift, but it's consistent and doesn't change when you increase or decrease the ND level. Also, the levels are smooth and clear, and there doesn't seem to be any distortion... which is extremely shocking to me.

Also... there is NO rattle or looseness in the ring, which makes me happier than it should, to be quite honest.

The adjustment putter makes it easier to adjust without getting your fingers on the edges of the lens (makes it easier to adjust if you need to turn up or back depending on the light... this is especially helpful with video).

I really only have 3 complaints, and they are extremely minor.

1st) As with any filter, I would really like to see K&F either add a magnetic mount option or add a filter tool to make it easier to turn on and off. I know someone will say that the "putter" makes it easier, but I don't trust putting pressure on a free-floating multi-piece filter.

2nd) The case it comes in is different from the other Nano-X series cases. It's more of a leatherette type, whereas some of the others are more suede/denim style.

3rd) Threaded front element. I know some people will say, 'You NEVER stack filters!!! '. Yes, well, there are a large number of photographers who do.... if you don't want to, fine... but don't argue against any possible functionality.

It works amazingly well and does not interfere with the image I want to capture. So the "complaints" above are more of a wish list than anything else.

Definitely recommend.

I use the variable ND filter very frequently, as I often work with long exposures due to my 'creative photography.' By adjusting the filter from ND3 to ND1000, I can easily achieve my desired aperture/exposure settings. I definitely recommend it.
