K&F Concept's range of filters have never let me down and neither has this variable ND3-ND1000 ND filter.
This filter maintains accurate color throughout the entire range unlike other filters I've used, which is a huge plus since it saves me time in post by not having to mess with color correction.
There is no dreaded "X", even when I intentionally went too far. While I'm not sure the stated range is entirely accurate, it is close enough and provides a ton of functionality, especially given the low price point compared to other filters that offer such a great density range.
I don't experience any vignetting with this filter, which isn't as slim as others I've used. But I rarely get vignetting when using the 18-140mm lens that I tested this filter with so my experience may not be applicable to different lenses.
Stops are clearly marked on the filter, and the adjustment is smooth with a little resistance that offers good control while shooting.
That said there is one thing you should know about this filter - YOUR LENS CAP WILL NOT FIT. I wish they included a lens cap with this filter or at least stated this clearly in the description, because you'll have to either print a new lens cap or buy one that will fit over this filter.
For the 67mm filter, you'll need a 72mm lens cap.
Overall this is an excellent value for a high quality filter. I doubt you'll find another variable ND filter with this range and at this quality for a lower price.

I have several different sized lens and several different brands of filters. Most are in this price with a couple less expensive and a couple of high priced premium brand name filters.
The majority of my filters in this price range perform like a lower priced filter. Some don’t quite fit on the lenses the way they should, some feel tight when I turn them, and most just don’t perform as a neutral density filter should.
This particular filter surprised me by surpassing my expectations. It feels solidly built. It looks good. The glass looks fine, and you can see it darken as you turn the lends. It’s waterproof, which is a nice touch!
I usually try to give a list of pros and cons in each of my reviews, but this lens filter seriously gives me nothing at all to give as a “con”. I will be buying additional filters from K & F. I see no reason to even try any others at this point.
I hope you have found my review to be helpful!

What can I say? This is a great tool. It gives so much flexibility for ISO speed and shutter speed. It has low distortion and internal reflection. This is a MUST on the front of any lens and the quality is amazing for the price!!!!

This is a third K&F filter that I own now, and it continues to impress me with the quality and value. This was an unknown brand for me and I can wholeheartedly recommend it to anyone now that I have used three different filters from them myself (UV, CPL, and this variable ND filters).
I am used to caring a set of ND filters with me in a case and I did want something more compact for different conditions. My approach is always to be minimalistic and to carry less. We travel a lot (a lit less now "thanks" to covid) and carrying less gear with me for convenience (and back saving) reasons is always nice. This filter performed superb on my recent trip to Turks and Caicos. We were in many super sunny situations and traveled a lot around the island. I am not a professional photographer but I would classify myself as an "advanced amature" and to my eye this filter is perfect. No color distortion that I can notice, no artifacts that I can see, great range, and convenience of multiple ND filters in one mounted on the camera! It rotates smoothly, stays in place, light, and seems to be very well built. Had it in some sandy conditions on the beach and it held up very well. Definitely recommend checking it out.

The first thing I noticed about the K&F concept 82 millimeter variable ND filter, is that it was packaged super nice, and when I picked it up out of the box it felt like a quality product. It had a super nice metal finish and the two pieces glided across each other very smoothly. This was my first time using an adjustable ND filter on my camera, but I was always looking for the extra versatility and adjustable ND filter could offer versus a fixed ND filter stuck at one particular stop.
This variable ND filter definitely did not disappoint, I love how easy it is to slap onto my lens and it's so great being able to switch and adjust the power of the ND filter with a simple twist of the lenscap. In addition to its obvious uses an ND filter, I love the fact that I feel like my lenses are more protected when this is on them as well because the glass is not exposed to the elements. Overall, I am definitely convinced about using ND filters and adjustable ones more specifically, so I would definitely recommend this to anyone who's on the fence about getting an adjustable one. This one definitely does the job.

The filter comes in a very elegant packaging with a magnetic closure and also has a small plastic box for transport. The filter can be easily turned on and off from the lens, intended for a maximum setting of 3-4 full f-stops. You can see the effect better in the backlight or strong contrasts in the subject, I'm looking forward to testing the filter in the midday sun in summer.

I bought the gradient filter because it was recommended to me by friends. After a few weeks of use I can say that I am more than happy with it. When taking pictures, it is necessary to make the sky darker (for example, at sunrise or sunset) so as not to get a burnt sky or a very dark foreground. This is where the filter shows its strengths. The filter can be easily placed in a suitable support without the risk of slipping. This provides beautiful images even with long exposures. To expand, I will add more filters of this brand later. I can give a clear purchase recommendation!

I use the filter both for filming with DSLR, as well as for long-term exposure during the day with open aperture, especially when filming, it is simply beautiful with open aperture. The ring is easy to turn. However, sound should be recorded externally, because the ring clicks quietly in the intended positions .. The packaging is ideal for transport and also withstands the attacks of my 1 year old daughter. The image quality looks good. At least I could not see any tint or other disturbances. I am very happy with the ND filter.
