Ich bin über das hervorragende Angebot an Objektivfiltern zum überzeugten K&F Fanboy geworden. Vor einigen Wochen hab ich mir auch einen Kamerarucksack und eine Softbox aus ihrem reichhaltigen Angebot zugelegt…soweit war alles Top. 

Dieser ‚Swirlfilter‘ reiht sich nahtlos in diese Erfahrungskette ein. Die Verarbeitung ist erstklassig und auch wenn ich diesen Effekt nicht häufig einsetzen werde, bin ich dennoch begeistert.

Wie immer…5 Sterne für das K&F Produkt.

Este es un filtro curioso por su efecto de espiral, que causa una distorsión en la imagen peculiar. Da la sensación de que la imagen gira sobre sí misma, lo que a simple vista resulta atractivo y, en principio, aporta un toque creativo a las fotos. Sin embargo, se nota que la transición entre la parte central de la imagen y el efecto de espiral es poco sutil, demasiado repentina, y no es lo que quieres cuando usas tecnología analógica, los filtros lo son, buscas naturalidad.

En cuanto a la calidad del producto, no hay pega que ponerle. El cristal parece resistente y se ajusta perfectamente al objetivo. La sensación es que se trata de un producto bien construido y duradero, como suele ser habitual en esta marca.

This lens filter has a fun gimmicky effect. I haven’t really figured out how to best use it. The transition from the clear image center to the halo is a bit abrupt and distracts from the aesthetics of the final image. The glass is pretty thick, probably about a half inch. Overall it’s fine for what it is, but it has pretty limited application.

When I first laid eyes on this K&F Concept 82mm Spiral Halo Camera Lens Filter, I was instantly captivated by its mesmerizing swirl pattern. As a photographer always on the lookout for unique ways to spice up my shots, I knew I had to give this filter a whirl (pun intended).
From the moment I screwed it onto my lens, I could tell this was no ordinary filter. The premium optical glass construction ensured crystal-clear image quality, while the spiral halo effect added an ethereal, dreamlike quality to my photos. Whether shooting portraits, landscapes, or cityscapes, this filter injected a touch of whimsy and wonder into every frame. That said, it did take some trial and error to find the right angles and lighting conditions to truly unleash the halo's full potential. But once I got the hang of it, the results were simply spellbinding. If you're looking to add a touch of magic to your photography, this filter is a must-have tool in your creative arsenal.

With the expected quality from K&F this attached without any problems to a 77mm lens. The filter is quite heavy and the thick glass prevents other filters being added.

In use, the filter produces interesting effects you can't easily replicate in software. Works best for still life, portraits where you can put a single subjects into the central non-distorting part of the filter.

Easy to overuse, but handy for a couple of images in a portfolio to add something different.

Der K&F Concept Nano B-Serie Halo Effektfilter ist einfach fantastisch! Der 67mm Filter erzeugt beeindruckende Wirbelverzerrungen und einen einzigartigen Tunnelblick-Effekt, der meinen Fotos eine ganz besondere Note verleiht. Die Verarbeitung des Filters ist erstklassig, und die Bildqualität bleibt trotz der Spezialeffekte hervorragend. Besonders begeistert mich, wie der Filter kreativ genutzt werden kann, um ungewöhnliche und visuell fesselnde Aufnahmen zu erstellen. Eine großartige Ergänzung für jeden Fotografen, der seiner Arbeit einen besonderen Effekt verleihen möchte. Sehr empfehlenswert!

I ordered this K&F Concept 82mm Spiral Halo Camera Lens Filter to use for special effects.

Basically, this filter consists of a large and heavy cone shaped piece of glass that introduces distortions. The center is a circle of clear glass that is distortion-free. This lets you take an image where the center is normal but the surrounding portion of the image is distorted and "swirly." This sort of effect can be useful for portraiture and certain landscapes when you really want to separate your subject from the background.

This filter is heavy. Because of its shape, you cannot attach other filters to it. If you want to use any other filters, you will have to attach them to your camera and then screw this one in. You cannot use any sort of lens cap with this filter as it projects out of the rim.

Construction is good. The filter screws into and out of my lenses smoothly. The sizing is spot on. Whiile you can expect some decreased sharpness in the center, I did not find it to be objectionable; this is not a filter you would use when critical sharpness is required. The convex shape of the filter also means that flaring can be a problem, especially when shooting outdoors under bright sunlight.

This is most definitely a special purpose filter with limited utility. That said, it does produce excellent results when used with an appropriate subject, aperture, and focal length.

This is a fun filter, 100% - but its practicality is a bit limited haha. But I like it, its fun! And its small enough to throw in the camera bag without really worrying about it too much (but the case is a bit big)
