82 mm Variable ND Filter ND3-ND1000, Ultra-thin HD, with Double-sided 28-layer Nano-coating, Nano-Xcel Series
SKU: KF01.2012
The KF Concept gray filter is - as usual from other products of the brand - high quality processed and comes in a safe and practical case.
Thanks to the special coating of the Nano-X series, there is no unwanted light interference in the image during use. In addition, the resistance to scratches increases, which I can really confirm here. Especially when I'm out in nature, I often come into contact with dust, dirt or other obstacles, which so far have not been able to cause any damage to the filter.
Here, the excellent functioning dust and water resistance of the filter is also to be emphasized!
As expected, the imaging performance of the filter is very good. The aperture stops can be precisely adjusted and are a blessing for my 28-75 2.8 lens. This allows for longer exposures with the aperture open and great bokeh in bright daylight. In terms of image sharpness, I couldn't notice any differences in images with and without filters. Only color-wise, there is a slight distortion towards warmer hues. But that's nothing that can't be cleaned up in post edit.
The filter can also show its strengths in the video area. Thanks to the stepless change of the aperture steps, as well as the easy and smoothly operable adjustment mechanism, smooth and quiet aperture transitions can be realized here. Especially with older cameras, this is a great advantage!
For such a performance, every hobby photographer should also be willing to dig a little deeper into his pocket. With this filter, the price of currently around 80€ is definitely worth it! That the image does not remain unaltered is clear from the outset with such filters. Since these changes but here compared to competing products but really keep within limits and can be subsequently ""wegbearbeitet"", this is not a point of criticism for me.
Accordingly, full 5 stars and a clear buy recommendation on my part.

Very wide range variable polarizer. I end up using this filter to get a few eclipse pictures, when the camera display only showed black with the high neutral density filter I bought specifically for the eclipse.

NEEWER has in my opinion once again brought a product on the market that makes you wonder - at least me!
The filter is delivered in a bag that is not quite practical in my opinion. Why not so practical? I'm more a fan of these hard cases, where the filter can be put inside. But is personal feeling, nevertheless, I did not want to let it go unmentioned.
The installation of the filter is kept very simple - filter out of the case, screw on and off you go. I use the filter on a Tamron 24-70mm 2.8f G2 and there this fits perfectly. No canting, or anything like that. What I've gotten used to: do not tighten the filter so much that you can not get it off later ;-) happened to me once, then never again *just saying*.
The filter quality I consider high quality and good. Well solved I find the rotary control to turn the ND filter in the desired position. A well thought out concept to not accidentally get your fingers on the glass.
For my purposes, as I use the ND filter, absolutely sufficient. The image quality is really great with filter in my estimation!
Price performance I find good and fair. I have had good experience with the filter!

The KF Concept gray filter is, as I have come to expect from the brand, very high quality workmanship. This is delivered safely packaged and comes in a beautiful and practical case.
Thanks to the special coating of the Nano-X series, it is ensured that no light interference is present here and it should also be more robust against scratches. Of course, there is still no absolute protection for it. The imaging performance is top and everything looks good even through the filter. The only negative is the representation of colors, because they are somewhat distorted by the filter.
However, the filter is not cheap in any case, but I am very satisfied with it all around.

Bought two of these and taped them together to take pictures of the Annular eclipse last October. I got some pretty good photos!

don't have much experience with Variable ND filters as they used to be such garbage, but it seems like the color cast issues are mostly mitigated now. I use this for video shooting and the little slide tab is a lifesaver to both gauge how far it has moved and to move it seamlessly in a shot. I have no complaints.

I'm using the 52mm variant on a Sigma C 35mm/1.4 for Sony and consequently can only say something about it.
In brief:
(+) good sharpness and color fidelity
(+) good workmanship and feel
(+) improved adjustment by grip lever (no problem even in cold weather with gloves)
(+) stepless and versatile
(+) nice and practical leather bag for storage
The first question I had was how the sharpness and color fastness would be with the variable ND filter. Here I have made in the past with other products so bad experiences that I ended up using these filters only in extreme emergencies. You can achieve such beautiful results with ND filters. Wouldn't it be nice not to have to carry around 5 different filters and still get good results?
Besides the use in filming, the filter is for me especially for long exposures (eg at the water) and open-aperture shots in sunlight of interest.
In all three cases, the filter can be used well. The only thing you have to be aware of is that you can no longer use the lens hood due to the small handle lever.
The operation works so well with this lever that you can also use and change the ND-FIlter while filming. On the tripod one notices then also no shakiness.
The SHARPNESS is surprisingly good and also color changes / color casts / etc. I could not determine. Therefore, there is already a big plus here.
The ND value can be adjusted continuously. Thus, however, the actual value is not recognizable. 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 an exact indication. So if you want to be a hobby mathematician and calculate exactly how to adjust exposure time and aperture, you will have a hard time.
For me personally, however, this does not matter in practice. I simply take a few minutes more time and, in case of doubt, achieve the desired result by trial and error.
Particularly when filming, however, I can already see in the live view what the result will be and here the filter only serves to adjust the final exposure for me. It fulfills this purpose very well.
The workmanship is of high quality. The filter is not the lightest or thinnest, but seems very robust, goes easily but not too easily and especially the thread can be screwed on without the hooking and canting, which one has otherwise often with filters. The screwed handle element underlines the high-quality condition of the filter and supports the already pleasant feel once again in a special way.
I also find the stylish leather case successful. It is designed to be quite valuable and the filter can be taken out of the bag easily and without fumbling through a simple mechanism. to do this, you simply pull on a strap on the side, which runs through the bag and thereby pushes the filter upwards.
Conclusion:
Good filter that delivers surprisingly good results and is very pleasant to use.
The workmanship and quality leads to a very good price-performance ratio.

It is an excellent filter, I like how it graduates and it is easy to use and adapt to my camera lens.
