The products from K&F are simply always amazing. The quality is convincing across the board. With the filter, I can easily adjust the aperture levels and that with absolutely top imaging performance. What more could you want. The filter is definitely worth the money!
Unfortunately, I don't have any photo examples right now, but such filters are used, for example, to make the water blurry/soft when the exposure time is too long and therefore the image is too bright. With all filters, you have to be careful not to screw them too firmly onto them. When it is extremely cold or extremely warm, you sometimes have real problems writing off the filters. That will also be the case with this one.

From the packaging to the actual filter, this screams professionalism and quality. The build quality is A1 and I like the included adjustment knob/flank because it makes navigating through the ND intensity much easier. The quality of the ND is incredible. My photos still retain their color and sharpness. I do make sure that I take a photo of a gray card or white card to custom white balance my camera as this can introduce a little tint - like most ND filters. The friction on this as you move through ND intensity is great. There's no slipping when I set where I want to go and there's no cross polarization which is very important. One thing that I wish this had is some sort of lens/filter cap. Polar Pro has gotten me spoiled yes, but it's a small addition that's key to keeping your filters protected as you move about. Not unless you plan on taking it off every time you move from one location to another. Other than that, this is a really great VND filter.

I like that the filter has a tab to use when adjusting it. It makes it so much easier to use than those that don't have the tab. It also has its own sturdy case to keep it from accidentally getting broken.
I haven't found anything that I do not like about it. :)

In my opinion, NEEWER has once again brought a product onto the market that amazes you - at least me!
The filter is delivered in a bag that is not entirely practical in my opinion. Why not so practical? I'm more of a fan of these hard-shell cases, where the filter can be put in. But it's a personal feeling, but I didn't want to leave it unmentioned.
Installing the filter is very simple - remove the filter from the case, screw it on and off you go. I use the filter on a Tamron 24-70mm 2.8f G2 and it fits perfectly. No tilting or anything like that. What I've gotten into the habit of: Don't tighten the filter to such an extent that you can't get it off later ;-) It happened to me once, then never again *just saying* I regard
the filter quality as high-quality and good. I find the control dial easy to turn the ND filter into the desired position. A well-thought-out concept so that you don't accidentally reach the glass with your fingers.
Absolutely sufficient for my purposes, as I use the ND filter. In my opinion, the picture quality is really great with filters!
I think the price-performance ratio is good and fair. I've had good experiences with the filter!

K&F Concept have been creating genre defining filters for many moons now. This is my second fave filter from them. 10 stops dynamic neutral density range? Are you serious?!?!?!? Landscapes have never been easier to photograph This is all you need to shoot a killer video in natural light without murdering your highlights. The color cast is nonexistent, the colors pop, and the quality of these landscapes are TOP OF THE LINE. From the wallet it comes in to the quality of the glass K&F is the BEST filter brand out right now they understand quality.

I use the 52mm version on a Sigma C 35mm/1.4 for Sony and can therefore only say something about it.
In brief:
(+) good sharpness and color fastness
(+) good workmanship and feel
(+) improved adjustment with handle lever (no problem even in cold weather with gloves)
(+) infinitely variable and versatile
(+) nice and practical leather case for storage
First I asked myself what the sharpness and color fastness look like with the variable ND filter. I've had such bad experiences with other products here in the past that I ended up only using these filters in an extreme emergency. You can achieve such nice results with ND filters. Wouldn't it be nice not to have to carry around 5 different filters and still get good results?
In addition to being used for filming, the filter is particularly interesting for long exposures (e.g. in water) and open-glare shots in sunlight.
The filter is easy to use in all three cases. You just have to be aware that you can no longer use the lens hood due to the small handle lever.
This lever is so easy to use that you can also use and change the ND filter while filming. You won't notice any shaking on the tripod.
The SHARPNESS is surprisingly good and I was also unable to determine color changes/color casts/etc. That's why there's a big plus here.
The ND value can be adjusted continuously. However, this also means that the actual value is not discernible. There is a scale with small squares, which are in the right place even when the filter is screwed on - but this does not replace precise information. So if you would like to let the amateur mathematician out and calculate exactly how you can/must adjust shutter speed and aperture, it will be difficult here.
For me personally, however, this doesn't matter in practice. I then simply take a few minutes more time and, if in doubt, I will get the desired result by trying it out.
Especially when filming, however, I can already see what the result is in live view and here the filter is only used for me to adjust the final exposure. It also serves this purpose very well.
The workmanship is of high quality. The filter is not the lightest or thinnest, but it looks very robust, is light but not too easy and, above all, the thread can be screwed on without the snagging and tilting that is otherwise common with filters. The screw-on handle element underlines the high-quality condition of the filter and supports the already pleasant feel in a special way.
I also find the stylish leather case successful. It is very well designed and the filter can be removed from the bag easily and without fiddling with a simple mechanism. All you have to do is pull on a band on the side, which runs through the bag and thus pushes the filter upwards.
Conclusion:
Good filter that gives surprisingly good results and is very pleasant to use.
The workmanship and quality result in a very good price-performance ratio.

I'm used to standard Neutral Density filters and having to buy various degrees of darkening lenses. Not so with this one. I was pleasantly surprise to see that with a sliding of the ring on the filter you can crank it down to very dark for a superlit sunny photo shoot or dial it back to almost completely clear. Or if I just want to decrease the depth of field, this lets me customize the amount of density to fit my lens. Great idea!
