K&F Concept 62MM UV Filter Ultra Slim Japan Optics Multi Coated Ultraviolet Protection Lens Filter with Lens Cap (Nano-K Series)

This UV filter is super value for money compared to premium brand filters. If you just want a filter to protect your lens while barely affecting light then this is as cheap as you'll get for a decent quality filter. The screw fitting is smooth. The cap is made from slightly plastic than premium brands, but works fine.

Although camera technology has moved on in recent years and UV lens filters are not perhaps as essential as they once were, they still offer benefits. Even if just as a first line of defence for your valuable lens, I'd much rather sacrifice a filter than a lens worth hundreds or even thousands of pounds.This K&F UV filter feels of good quality and comes complete with a lens cap and wrist strap. I went for the 82mm size to use with my Sigma 70-200mm f2.8 Sport lens as I take a lot of motorsport photography were it is not uncommon to find bits of stones and gravel flying towards you, especially if you're stood in the firing line at a rally stage, therefore having a filter on is an excellent way to ensure your lens is protected.I had no issues threading it onto my lens and both the included lens cap and my original Sigma lens cap fit the filter just fine.

This UV lens filter is simple enough. I am not a professional photographer, so my standards are not going to be as high in terms what is acceptable. For me, I do not find that this lens filter distorts my photos, nor does it add any light diffraction to my shot. I tried this filter on both my standard 17mm-50mm lens as well as zoomed on my 400mm. Comparing shots, I do not see any major differences between the two (with filter and without).I would have liked this filter more if it came with a better case instead of a plastic square container that does not even close up tight. Other K+F lens filters I have came with a round case that was the size of the filter. It also closed up tight around the lens. Of course, the other filters I have are not at this price point ($20 at the time of this review), so it is probably also a “you get what you pay for” situation.Overall, as I had mentioned, I am not a professional photographer, so I am not as picky with the results as some others might be. Seeing that there is not a lot of visible differences with my shots between having the filter or not, I think this is a good level filter to have if you are starting off. They are on the affordable side and will let you get your feet wet.

I own quite a few filters (UV, ND & CPL) and other products from K&F. This UV filter came in a square plastic case with a lens cap and lens keeper. The filter was clean out of the box. I got this filter for my Nikon 20mm f2.8D lens. So far, I was using the lens without a filter but got one to protect the lens front element when shooting outdoors. Both the K&F or the OEM lens cap fits well over the filter.I do not use a filter when shooting indoors. Even outdoors, I tend to use one when shooting in dusty environments and only on lenses that do not have a hood. It is a piece of extra glass that we put over the lens, it will have some minor imperfections which may be visible if one is a pixel peeper.This filter is good, I did not notice any degradation in image quality on pictures I have shot so far. Even though I do not use it indoors, I took some pictures to test, and did not notice any differences with or without a filter.The lens cap is ok but not as good as the OEM cap. The pinch is not deep and does not provide a good grip. The lens cap keeper is a waste, I cannot tighten it over the lens barrel and so won’t be using it.For $10.99, nothing to complain about, this is a good filter with lens cap, helps protect the lens against dust, scratches and fingerprints.

Personalmente non ho mai utilizzato filtri UV sui miei obiettivi fin ora, li ho sempre visti come una protezione, ma al tempo stesso capace di "peggiorare" più o meno la qualità delle immagini (essendo comunque un vetro in più).Da premettere che non sono un professionista (con tutte quello che ne deriva), ho scelto un filtro da Ø77 così da poter almeno proteggere la lente con Ø più grande che possiedo al momento.L'ho portato con me nelle ultime uscite e onestamente non ho notato perdita di qualità (all'inizio ho fatto qualche prova con e senza filtro), ho quindi deciso di lasciarlo montato, almeno quando scatto all'esterno.Il filtro è comunque molto sottile e si installa senza problemi.Non mi piace molto il tappo in dotazione, si aggancia bene ma lo sento meno stabile di quello originale Sigma dell'obiettivo. Bene comqune da avere di scorta.Il rapporto qualità/prezzo è ottimo, se non altro da usare come protezione per lenti un po' più grandi.

Petit kit comprenant un filtre UV 82mm, un bouchon d'objectif 82mm et une petite dragonne élastique pour le bouchon d'objectif. Lorsque je pars en ballade photo dans la campagne / en forêt aves des amis, entre les branches qui peuvent revenir en boomerang, les ronces et autres végétations épineuses ou simplement la poussière, la sève d'arbre ou autre, en tant qu'amateur qui n'a pas forcément les moyens/l'envie d'assurer son matériel ni surtout de le remplacer, j'apprécie de savoir que la lentille frontale de mon objectif est protégée.Que ce soit sur mon boitier en 30Mpx ou celui en 24Mpx, même avec mon Laowa Macro 100mm le plus piqué dans 95% des cas il n'y a aucun impact visuel notable entre avec et sans le filtre. Pour du paysage, du portrait ou du studio en tant que pro avec du matériel bien plus cher mon point de vue aurait été différent évidemment. Mais là en amateur l'impact négligeable sur la netteté est largement compensé par la gain de protection.Le bouchon d'objectif est lui aussi plus que bienvenu, construction plastique classique, très bien, même si celui d'origine de mon objectif va bien sur le filtre aussi, le bouchon me sera utile pour des filtres créatifs avec step up ring sur des objectifs de diamètre différent. La petite dragonne elle, je ne me vois pas vraiment l'utiliser du moins pas pour faire pendouiller le bouchon d'objectif à l'objectif lui même, elle est même plus gênante qu'autre chose sur le bouchon je trouve.Pour 18€40 au moment du test le kit est très bien.

No tenia ningún filtro para mi actual objetivo de 72 mm así que, esta ha sido una oportunidad para adquirir uno.Nunca he sido muy de usar filtros, salvo raras ocasiones, pero no esta mal tener alguno para proteger la lente de tanto sol, que cada día es peor en general, quema más y sobretodo ahora en verano.Iré probando a ver si me convence para dejarlo siempre puesto como una protección extra.A primera vista, bien, contento con el producto.
