In commercio vi sono diversi tipi di filtri CPL di diversa qualità, fattura e ovviamente prezzo.Per chi non vuole spendere tanto i prodotti di questo marchio possono fare al caso vostro grazie all'ottimo rapporto qualità prezzo.Anche in questo nuovo tipo di filtro con la nuova tecnologia vennero particelle la qualità è davvero ottimo sia a livello costruttivo sia a livello funzionale, avremo un filtro magnetico che andrà ad applicarsi su un ring che è precedentemente avviteremo al nostro obiettivo così da poterli poi applicare tutti i filtri magnetici che abbiamo in possesso.Questo filtro ha una caratteristica particolare rispetto ai precedenti, la tecnologia nanoparticelle è un rivestimento che gli garantisce un'ottima impermeabilità all'acqua, ovvero le piccole goccioline d'acqua scivoleranno molto più facilmente sul vetro non lasciando tracce che possono macchiare o creare aloni alla lente.Il filtro in sé funziona molto bene come tutti i filtri di questo genere girando il filtro in senso orario o antiorario applicheremo più o meno questo genere di filtro che andrà a tagliare o comunque a ridurre i riflessi e le luci soprattutto su superfici riflettenti come vetri ed acqua o anche sui capelli andrà a togliere il riflesso della luce creando un capello più omogeneo e meno luminoso.Un buon prodotto da tenere sempre con sé per le varie occasioni dove i riflessi possono danneggiare le nostre creazioni fotografiche.

Ich habe mir den Polarisationsfilter von K&F gekauft und bin absolut begeistert. Dies ist nicht mein erster Filter von K&F, und ich muss sagen, die Qualität des Unternehmens beeindruckt mich jedes Mal aufs Neue.Die Verarbeitung des Filters ist erstklassig. Er fühlt sich robust und hochwertig an, was in dieser Preisklasse nicht immer selbstverständlich ist. K&F hat es wieder einmal geschafft, ein Produkt zu liefern, das nicht nur funktional ist, sondern auch ästhetisch ansprechend.Die Verpackung ist, wie immer bei K&F, sehr gut. Der Filter kommt sicher verpackt an, sodass keine Beschädigungen während des Transports entstehen. Alles ist sehr ordentlich und professionell verpackt, was ich sehr schätze.Ein besonderes Highlight ist die magnetische Befestigung des Polfilters am Objektiv. Das ist ideal, um schnell mal ein Bild ohne Filter zu schießen, ohne lange fummeln zu müssen. Einfach abnehmen und wieder anbringen – genial!Die Qualität des Filters ist wahnsinnig gut. Wenn montiert und man diesen gegen den Uhrzeigersinn dreht, sieht man direkt die Änderung. In diesem Fall minimiert der Filter Reflektionen, was gerade bei Wasser- oder Glasoberflächen einen enormen Unterschied macht. Die Farben werden kräftiger und die Bilder klarer.Ich liebe diese Firma und ihre Produkte. K&F hat mich noch nie enttäuscht. Heute sogar im Angebot am Prime Day für nur 20 Euro – da musste ich einfach zuschlagen!Fazit: Der Polarisationsfilter von K&F ist ein absolutes Must-Have für jeden Fotografen. Er bietet hervorragende Qualität, ist leicht zu bedienen und die magnetische Befestigung ist ein echter Pluspunkt. Klare Kaufempfehlung!

I have seen these magnetic filters being marketed for a while now, so decided to see if they are an improvement over the screw in types.Bottom line...yes they are worth it.The 'receiver' ring is quite thin. I would suggest you keep it attached to the filter when not in use...someplace safe. I think it could be bent fairly easily otherwise.The knurling on the side could be deeper in my opinion, and why I gave it 4 stars over 5.That being said, I really enjoyed using this filter. The polarization seemed nice and tight.The convenience of slipping the filter on and off makes this special...it only takes a second to put on and off.I will be looking for more mag filters from now on from K&F.Good show here...recommended.

I’ve been a fan of K&F Filters and accessories for some time now, and have come to appreciate the consistency and quality of the brand. The majority of my lenses live their lives with K&F UV protective filters on their front element.Like many others, as the caliber of mobile phone imagery and videography have improved to levels of near professional quality, I’ve begun to concentrate more energy into taking advantage of those attributes, not to mention the portability. Both in videography and photography, whether using a full-size camera or a high-end mobile phone, I consider a CPL filter essential. It also has the effect of neutral density.In hand, the K&F Concepts Magnetic Circular Polarizer Filter System gives the impression of quality. Between its matt black finish, the 52mm magnetic adapter ring and the reflection of the rich multi-coatings, it’s an impressive filter. Interestingly, despite the fact that the adapter and filter are attached magnetically, the CPL still rotates freely, as is necessary to adjust its angle; it must be magic.The only disappointment in the system for me is the lack of usable threads on the front of the CPL; I prefer to use lens shades and would like some means of attaching them. Or to have the option of stacking another filter or step-up ring onto the system. That said, step-up/down rings with appropriate 52mm threading can be attached to the threaded adapter ring, for example a 49mm – 52mm step up ring will allow the use of the 52mm CPL on a 49mm threaded lens. On the other hand, the lens I’ve included in the pictures takes 52mm filters and its built-in lens shade works fine with the 52mm K&F Concept Magnetic System, but the lenses front cap doesn’t. I’ve looked through the K&F Concept Store and they have a number of other magnetic filters, filter sizes and adapter ring combinations in their magnetic eco-system, most of which do include a magnetically attachable front lens cap, including circular polarizers; why they don’t include one with this combination I wouldn’t know, but I think they should. The convenience of the system is negated if in order to protect the font element of my lens I need to unthread the adapter ring in order to place on a lens cap. I didn’t note anywhere in their Amazon store that a compatible magnetic lens cap is being sold separately.In my view, a complete system, and I’m not referring solely to K&F Concept in this regard, would include magnetically attachable lens caps and lens shades as part of the eco-system. Or if not that, front threads on the attached filter, or corresponding adapter rings, that are the same size as the rear threads of the adapter, allowing for a more versatile system, and one that would accept the users currently owned screw mount filters.In any event, I have complete confidence in the quality of K&F Concepts filters and their products generally. They are a reliable company that stands behind their product lines. If you’re interested in a magnetic filter system, including this one, I suggest perusing the K&F Concept Amazon Store to see all of the available options. Have fun.
