I am a fan of K&F Concept and love the fact that they can produce quality products at affordable prices.

I obtained this filter with an 82 mm diameter thread, and it attaches to the lens beautifully. However, like a lot of filters, it is easier to access with the lens hood off the lens. In this case, I have found that better results are achieved with the lens hood off. The more light across the filter, the better the result.

A nice storage case is provided with the filter, so there is very little chance of it getting damaged when it is tossed into a camera bag.

Further use, and, some decent weather, should see my results improving!

Un filtro curioso. Al colocarlo delante del objetivo de la cámara, se logra un efecto flare lineal similar al que se obtiene con lentes anamórficas, lo que añade un estilo visual atractivo y artístico a las tomas, y si lo planeas bien, hasta cinematográfico.

El filtro se nota que es de calidad. Entre sus capas, incluye filamentos dorados que son los responsables de crear esas líneas de luz en las imágenes. Esto funciona especialmente bien cuando se trabaja con luces intensas o reflejos, generando destellos. Aunque por las noches no es tan efectivo. Las líneas de luz pueden volverse demasiado prominentes cuando hay muchas fuentes luminosas, como faroles o luces de los coches, lo que puede saturar la imagen y hacer que la composición sea demasiado confusa.

Es un efecto que puede ahorrar mucho tiempo y dar mejores resultado que lo que se haria en postproducción, pero desde luego hay que usarlo con mesura. Está claro que no es una lente anamórfica, pero da el pego, sobre todo cuando los presupuestos son limitados.

Bien que vendu pour simuler les flares de lentilles anamorphiques, je trouve cet effet plus utile pour créer des rayons de lumière diagonales autour de lampes.
Le filtre est de bonne qualité, il se visse et tourne sans problème, et il garde bien son orientation. Il est fileté sur le devant afin de permettre d'ajouter un autre filtre à l'objectif.
Il semble un peu plus cher que la compétition, et étant devenu un adepte de K&F Concept je n'ai pas encore testé de filtres streak d'autres marques !

The filter effect makes a high-quality impression and can be easily screwed onto the lens thread. It is particularly practical that you can rotate the filter, similar to a CPL filter, to change the direction of the light strips. This offers great options and gives you full control over the effect.

The filter is ideal for creative photography, especially when it comes to staging light. The effect works best when there are smaller light sources in the image, such as fairy lights or car headlights — but with larger lights, you shouldn't be too close to the light sources to achieve the desired effect. The lights are drawn out and create this characteristic anamorphic look.

For me, this filter is a great addition to photo equipment, especially for effective shots that need that little bit extra. The filter not only offers great effects, but is also robust and easy to handle. A storage box is included so that you don't scratch the glass during transport.

The filter does not noticeably reduce the image quality, it just drags the lights out. What is a bit irritating is that the description says that the lines should be blue transparent, at least that's how it was written at the time of writing this review. However, the lines take on the color of light. For example, I photographed a reddish string of lights and the lines were also in the same color, but not blue. Personally, I think that's better because you're not limited to one color, but the colors match the overall picture better.

All in all, I can give this product 5 stars and also recommend buying it.

As with most K&F products I've tested, the build quality of this filter is very good and there didn't seem to be any issues with unintended alterations to the image. I've been pretty impressed with K&F products as a whole, actually, and this is no exception. The gold streak effect is pretty awesome and something that I have been interested in trying for a while due to it's uniqueness - I've just scratched the surface with the creativeness that this filter can provide and look forward to using it in different situations. Having said all that, I don't think there's any way I could have justified buying this (it was a free review product) for the cost. The 52mm that I picked up is listed for $32 and obviously the larger the filter the more it costs. $32 is definitely not super expensive when it comes to photography gear but the cost-to-use ratio wouldn't be in my favor as this is an ultra specific filter that will only be used sparingly. I have K&F diffusion filters that never leave certain lenses because they have an in-camera look that I love. This filter definitely wouldn't fall into the same category. It is a really nice filter though and if you're looking for something like this then the K&F would be something to consider.

Quando ero ragazzo, negli anni 80, nel corredo foografico di mio padre abbondavano i filtri per effetti speciali, tra cui quello per fare le stelline attorno ai lampioni e quello per fare le strisce.
Poi, il gusto estetico è cambiato, e questi tipi di effetti speciali sono caduti in disuso.
Con l'avvento del digitale, molti filtri fisici sono stati sostituiti da altrettanti effetti generati dai software di post produzione.
Visto però il ritorno in auge dei filtri "star", "cross" e come questo "gold streak", montati sulla lente e non generati dal computer, evidentemente gli effetti digitali non sono ancora soddisfacenti quanto quelli ottici.

Ho preso questo K&F per curiosità, grazie al programma Vine. Fa parte della linea "buona" del produttore cinese, quella denominata Nano-X. Non ho ancora ben capito la differenza tra le tre serie di filtri K&F, Nano-K, Nano-D e Nano-X, se non la presenza crescente di strati antiriflesso, 18, 24, 28.
Anche la qualità del vetro ottico utilizzato dovrebbe essere superiore.

Fatto sta che questo Nano-X Gold Streak, fa bene il suo lavoro, creando esattamente l'effetto per il quale viene venduto, cioè le righe dorate attorno alle luci puntiformi, senza impastare l'immagine e senza introdurre dominanti o impastare l'immagine.

Ho però notato due problemi:
1) va fatta molta attenzione a non stringere alla morte il filtro altrimenti diventa molto difficoltoso svitarlo. Basta portarlo a battuta, non si svita da solo.
2) in alcuni frangenti la messa a fuoco può venire ingannata dalle strisce dorate. Non è un difetto del filtro, ma è fisiologico. Meglio quindi impostare la messa a fuoco a punto singolo, anche perché con questi filtri, di solito, si scattano foto di paesaggio urbano o comunque statiche.

La realizzazione è davvero buona, con una verniciatura opaca molto bella (forse è anche quella che rende più duro svitare il filtro) e un trattamento delle lenti dall'aspetto meraviglioso, oltre che idrorepellente.
Custodia un po' grande perché destinata a tutti i diametri (il mio è da 67, ma la custodia può accogliere anche quelli da 82), ma ben fatta e con una rastrelliera che non fa cadere il filtro nemmeno se apriamo la scatola al contrario.

This company makes high quality everything and the price is so much more reasonable. Sure, you can recreate this digitally, but it never looks quite right. Give these a shot to add a little flair.

The K&F Concept Nano-X Series Gold Streak Anamorphic Effect Filter is simply great! With its 67mm diameter, the filter creates beautiful golden stripes and anamorphic light reflections that give my pictures a unique, cinematic look. The workmanship is top-notch, and the Gold Streak design brings amazing visual effects to my photos and videos. The filter is easy to use and fits my lens perfectly. Ideal for anyone who wants to give their recordings a special flair. Highly recommended for creative photographers and filmmakers!

I own several K&F products and I've always been impressed with the quality of their products. This filter is no exception, it's a quality product. It is of course a very specific use filter, but it works great if your intent aligns with its purpose.

In a world where photo editing (lightroom/photoshop) is so prominent some might argue this effect could be added in post but I prefer to capture with my camera and do minimal post-processing. This gives you the ability to capture neat shots with an artistic/cinematic feel straight from your camera.

Overall I'm quite happy with this filter and it will make a great addition to my collection of photographic equipment.
