First and foremost, I have to say that I am pleased with my purchase of this particular Variable ND Lens Filter as someone (I'm a non-professional photographer) who has recently become interested in such kit/capability and don't wish to spend $100+ on higher-end equipment.
I see its greatest value in situations where time is of the essence and you are not able to fully control the situation - i.e., you don't have the luxury of time to set up shots using/switching fixed ND filters.
PROs:
*Doesn't appear to affect sharpness in any discernable way - The glass is of sufficient quality.
*Threading is tight and of good quality - Does not back-out when rotating the ND ring opposite to the way it is threaded on.
*Any color hue created in the lower ND settings is not too noticeable and is easily corrected in post. In several instances I've actually been pleased with the very slight hue it created and left it that way.
*The ND ring is tightly fitted but turns smoothly (no issues with it turning by itself when carried around all day - it seems to stay in place).
*Appreciate the plastic case it comes with to keep it from being damaged or collecting dust.
*Did not appear to affect my camera's autofocus and/or face detection.
*Probably obvious, but it's WAY faster to adjust this than removing and replacing fixed filters. This was handy when I was on a guided tour and in a vehicle where I didn't have time to change filters for particular shots, a common benefit probably to all variable filters of this type.
CONs:
*It does add a couple mm of length to your lens, but I suspect nearly all filters like this will do the same. If your camera/lens are already tightly fitted in your bag, having this filter on it could amplify the issue.
*No audible/tactile "click" when adjusting, although as stated before it's machined tight enough I never had any issues with it wandering from where I set it after several hours of walking around. More of a personal preference.
Summary:
For the money and its quality (at this price-point) it's sort of a no-brainer for someone like me who is/was interested in adding ND filter capability to outdoor photography, particularly landscape photography that can be troublesome during maximum lighting conditions (high noon) which can wash-out some contrast in your shots.

So, I have to say that this filter is a first for me and I am highly impressed. There are times when the sunlight can be quite harsh and I don’t want to go up or down stops. The filter performs well in bright sunny days. It’s made well and has a good sturdy feel and weight to it. I’m currently using on a 35mm 1.8 Sony lens. I cannot wait to put it through its paces this summer. Well worth its asking price.

Die Qualität ist gut und mit anderen Markenprodukten sowie Produkten der Marke K&F Concept vergleichbar, die ich mir schon vorher gekauft hatte.
Das Produkt kam sicher verpackt an, als Beigabe waren 3 Mikrofasertücher aus feinem, weichen Jerseymaterial enthalten, die ich nicht zwingend brauchen würde, aber die einen guten Eindruck machen.
Der Filter ließ sich ohne Probleme an meiner Nikon Z50 montieren, durch den dicken Ring am Filter ist jedoch der Blendschutz dann nicht mehr ohne weiteres nachträglich montierbar.
Die Bildqualität ist gut, es treten keine Farbverfälschungen auf
Da der variable Filter (wie alle Filter dieser Art) auf 2 Polfiltern basiert, die gegeneinander gedreht werden, tritt aber insbesondere bei geringen Abdunklungen aber ein Polfilter-Effekt im Foto auf.
Das ist aber nicht schlecht, und bei anderen variablen ND-Filtern ebenfalls der Fall. Häufig benutzt man ja sogar absichtlich Polfilter um Reflexionen zu minimieren, aber es sollte einem bewusst sein. Anders als bei regulären Polfiltern ist die Polfilter-Ebene hier nicht drehbar.
Beim Beispielfoto von einer Hecke sind die Effekte sichtbar. Das Bild ohne Filter (links) ist bei sonst identischen Kameraeinstellungen fast identisch zum Bild mit dem Filter voll abgedunkelt (rechts), außer dass ich die Belichtungszeit von 1/10s auf 30 Sekunden verlängert habe. Hiermit könnte man durch die lange Belichtungszeit gut verwischte Aufnahmen von bewegten Objekten (Wasser, Autos, etc.) machen. Mit dem ND-Filter auf niedrigster Stufe (mitte) sind die Reflexionen auf den Blättern durch den Polfilter deutlich reduziert, sie wirken viel grüner. Von den anderen Zwischen-Einstellungen des Filters habe ich kein Foto gemacht, aber es treten ebenfalls keine besonderen Farbabweichungen auf.
