Guter Filter, der mit der teureren Konkurrenz mithalten kann. Sehr ansprechende Verpackung und praktische Aufbewahrungs-Hülle.

Perfect -good quality as always from Smallrig!

Always a fan of the K&F quality of filters and matte boxes. I shoot with anamorphic lenses, and still get no vignetting at all. The build quality is awesome and reassuring. Amazon broke one of my filters in shipment, and K&F replaced it so quickly. An awesome experience all-around

Top in der Verarbeitung! Passt alles! 👌

Super qualität, vielen Dank.👍❤️

Black mist 1/4: mucho mas sútil que la versión de rosca de la marca. Es muy suave pero se nota. Además, no tiene ese color shifting de temperatura cálida que tienen los de rosca. Me tiene tan contento que lo tengo fijo en la camara.Es bastante grueso y se ve muy resistente.Yo lo monto en un smallrig matte box mini.

At about 4mm thick, with its measurements of 4” x 5.65”, the K&F Concept UV Cinema Filter is a pretty hefty chunk of glass, and with all those coatings, on both sides, a beautiful thing to behold. A UV filter is generally used to, you guessed it, block UV light from a light sensitive material, and very often as inexpensive insurance to protect the front element of expensive lenses.I have a number of K&F Concept filters, most of my lenses live their lives with a K&F protective filter on their front element. I also own some of their other photo/video accessories as well; I consider them a trusted manufacturer.As the seller asserts, their Cinema Filter is sized specifically for Tilta and Smallrig mini matt boxes, although there may be other manufacturers that I’m not aware of. A matt box, that fits onto the front of a lens, is basically used for two purposes, as a filter holder and a lens shade. In the case of the Tilta MB-T15 matt box I use, there are grooves on the leading edge into which the filter slides and is held snuggly in place.Handling the filter takes some care, since it is not enclosed in anything, for example a frame, but is glass from edge to edge. In our case, we keep cotton gloves around for such situations, and use them when handling the filter. Oddly, K&F Concept has always provided a cleaning cloth with every other filter I’ve acquired from them, but not in this case; it would be nice if they did, but I’m not complaining.The filter arrives in retail packaging, with a magnetic closure, that is a storage case unto itself, however the actual filter case, that gives the impression of faux leather, is exceptional. It has a flip open flap with a bright orange nylon strap attached that when pulled, slides the filter up and out, making it convenient to grasp from the edges. The inner lining of the filter case appears to be soft cotton, although I am not certain of that.I ran three tests with the filter: one to check its exposure accuracy, another to check whether it diminishes the sharpness of the transmitted image, and a third to check the effectiveness of its UV blocking. I included results for each.For the exposure and sharpness tests, I photographed the lettering on the back of a box of cake mix, under artificial light. In the case of the exposure test, I simply calculated the exposure with the UV filter applied, and made the exposure. I then removed the filter, and made another exposure without changing the camera settings. I found that the filter has no significant effect on exposure; both exposures were recorded with the histogram in the same range.For the sharpness test, I used the same two images, with and without the filter, and enlarged them 500%. In this case, again, I found that the filter did not diminish sharpness to any significant degree, which is surprising given the thickness of the glass. I provided the pictures and labelled them.To test the filters UV effect, I shot the same outdoor scene, at the same camera settings, with and without the filter. To my eye, it may have reduced UV a tiny bit, but not enough to matter. That said, modern digital sensors, unaltered, record the entire spectrum of visible light, as well as most of the spectrum of infrared and ultraviolet light. In order to record only visible light, manufacturers install what is called an IR Cut Hot Mirror filter over the digital sensor and its Bayer Array of most off-the-shelf digital cameras. Digital cameras sold without this filter are referred to as a “Full Spectrum Camera.” If you’re not sure whether your camera is full spectrum or not, it isn’t; full spectrum cameras produce a result similar to that of infrared film.UV filters are effective when recording on film, but have little added effect when capturing with a digital sensor that already has a UV filter installed by the manufacturer. In the case of my digital imaging, I use UV filters to protect the front element of expensive lenses. And in that respect, the K&F Concept Cinema UV Filter can provide the same protection for expensive cinema lenses without impacting camera settings, in effect providing relatively inexpensive insurance.The physical quality of the K&F Concept ND Cinema Filter, and its coatings, along with the provided case, appear outstanding. I’m looking forward to using the filter in a live shooting situation.

I mostly shoot with spherical lenses, so thought this might be fun to get those anamorphic style flares from hard light sources.My first impression upon opening are really good. The leather-like pouch feels really nice and has a very useful pull tab that lifts the filter up out of the pouch so you can grab it without getting fingerprints on the faces. I wish more filter pouches used a similar setup. The 4x5.65" filter is a standard in the cinema industry and fits in perfectly with my filter kit and is properly sized for a standard matte box tray.I took a couple photos with my phone that demonstrate how the filter works. As you can see, harder light sources add that traditional blue anamorphic streak across the frame. I feel like blue is very sci-fi and works well in those scenarios, as well as some music videos. It's a bit intense for general use, in my opinion, but for a filter this cheap, it's worth having in my kit for those infrequent times I want to get this specific look. Usually streak filters like this are far more expensive, but this has similar results to those higher priced options.I've been quite happy with my assortment of K&F filters and feel like they punch way above their price point, competing with filters much more expensive. This is yet another perfect example of K&F doing it right and saving me a bunch of money. Would recommend.

Moins pratique qu’un filtre variable rond mais sans doute meilleure qualité d’image quand on a du temps.En effet la mise en place sur la matte box Smallrig n’est pas évidente : dans quel sens? Risque de faire tomber le verre sur le sol, frottements du cadre sur la matte box etc…ce n’est pas la faute de K&F mais celle de Smallrig. Prix intéressant par rapport à certains autres filtres carrés PRO.

Solche Details sind wichtig, besonders wenn man in professionelles Videoequipment investiert. Die Verpackung schützt den Filter nicht nur optimal während des Transports, sondern macht auch das Auspacken zu einem besonderen Erlebnis.Bauqualität und Design:Die Verarbeitungsqualität des Filters ist hervorragend. Mit einer Dicke von 4 mm fühlt er sich robust und langlebig an. Das Design ist professionell und passt perfekt zu meinem 4 x 5,65" Matte Box System. Die Kompatibilität und einfache Handhabung sind große Pluspunkte.Leistung bei Außenaufnahmen:Bei Außenaufnahmen zeigt der Black-Mist 1/4 Filter seine Stärken. Er liefert eine hervorragende Bildqualität und hilft dabei, die Lichtstreuung zu kontrollieren und das Gesamtbild weicher zu gestalten. Dies ist besonders nützlich bei Aufnahmen mit starkem Licht oder bei der Erstellung von Stimmungsbildern.Einsatz im Videobereich:Als Videograf schätze ich die subtile, aber effektive Wirkung dieses Filters. Er verleiht den Aufnahmen einen kinoreifen Look, ohne dabei die Natürlichkeit des Bildes zu beeinträchtigen. Die Reduzierung von Blendung und Reflexionen ist ein weiterer Vorteil, der in vielen Aufnahmesituationen nützlich ist.Fazit:Der K&F Concept Nano-X Black-Mist 1/4 Filter ist eine ausgezeichnete Ergänzung für jedes professionelle Videoequipment. Seine hochwertige Verarbeitung, die einfache Handhabung und die beeindruckende Leistung bei Außenaufnahmen machen ihn zu einem unverzichtbaren Werkzeug für Videografen.

The box, carry pouch and filter itself feel like buying a lot more expensive product.It's all of great quality and feels premium. The filter itself seems nice, I did some quick tests. I don't think you can go wrong with a Mist type filter on the lowest density.

Kurzum ein super Effektfilter mit 4 x 5,65" Standard für gängige Matte-Box Systeme. Der 1/4 Mist-Filter wirkt wie ein Weichzeichner und sorgt beim Filmen für einen ansprechenden Look (Blooming bei Highlights / Lichtquellen, Hazey-Look). Es ist gut einen solchen im Arsenal an gestalterischen Mitteln zum haben.Dank der Nano-Beschichtung ist der Filter auch einfach zu reinigen, Schmutz und Flüssigkeiten perlen förmlich ab und er ist bspw. gegenüber Fingerabdrücken resistent. Sehr zu empfehlen.
