K&F Concept 67mm Variable ND Filter ND8-128 Adjustable Fader Neutral Density ND8 - ND128 Filter, NO Spot X Black X Issue, MRC 28-Layer, Ultra Slim, Waterproof (Nano-X Series)

A very nice ND filter for the price, no noticeable effect on sharpness for video work (though not tested with high resolution photography) and minimal issues with flaring in bright sunlight so the coatings work quite well. As long as you use it within the specified ranges you won't see the typical X pattern of variable ND filters. Does what it needs to do without detriment to image quality, which makes it a pretty perfect filter for the price.

It works fine with my normal spectrum camera even at ND 128 there is no cast to be seen as in shot 3. The vignetting is due to a DX lens being on a FX camera and is nothing to do with the filter.Shot 1 is ND 128 on a full spectrum camera, shot 2 is the view from a full spectrum camera without the filter. ND 8 is just a paler version of shot 1.

The two photo's were taken on a Nikon with a kit lens 18-105mm. K&F Concept have got this so right, as it states in the description, no X Factor or Vignetting. The photos look like they have a slight blue colour cast, but this can be put right in post. Over all, a good filter. I would highly recommend to photographers that are looking to slow their shutter speeds.

When the filter is attached the ND indicators are at the bottom, not the top, so it's impossible to see what setting they're on unless you turn your camera upside-down. This filter leaves a lighter patch in the bottom right of the image, making it absolutely useless. Do not buy.

This is my third and I'll try the new release next. K&F delivers again, prooving these can be produced and sold for a reasonable price.

Great quality glass. The price was reasonable. The variable filter provides extra flexibility and saves space while travelling. This is key for me as I travel a lot and like to travel as light as I can. I did not experience any chromatic aberration, loss of definition or the dreaded X.Overall great product.

This filter is great for the price point. The packaging is excellent along with the build quality. The filter is smooth when transitioning between ND8 and ND128, however it does not feel loose and does not move accidentally once used. great product at a great price

Bought this filter for my friend as a birthday present. She loved this filter. She is starting as a photographer. She said it is very easy to use, easy to install and easy to clean.

Difficile trovare di meglio a questo prezzo, va detto! Tuttavia, ci sono prodotti superiori, ma 4 volte tanto questo prezzo.Vale la pena spendere di più?Dipende! Se sei un professionista probabilmente si, anche se con un pò di competenze si possono aggirare i problemi.Per tutti gli altri utenti è la soluzione migliore su questa fascia di prezzo.A mani basse da comprare! Ottimo per le foto ed altrettanto per i video.Non sono solito dilungarmi sui dettagli tecnici perchè chi cerca prodotti di questo tipo solitamente si guarda qualche video dimostrativo e si informa molto, quantomeno sa di cosa si sta parlando.Unica pecca: la mancanza di un tappo infatti si graffia facilmente e bisogna prestare molta attenzione.AVVISO - Su molti obiettivi non si potrà utilizzare il parasole o sarà molto difficile montarlo.

La qualité est au rendez-vous !

Perfeito para vídeo. Tinha um ND 4-32 e havia situações em que faltava um pouco mais de bloqueio da luz, principalmente em dias com sol muito forte. Com este filtro nunca mais tive esse problema, é perfeito! A única coisa que posso apontar é que rosca é um bocado difícil de meter na objetiva e o filtro não roda suavemente. Mas por este preço não me queixo.

Pas de croix, pas de changement de couleur, tres bien!

Es ist etwas verwirrend, dass die Namensgebung der ND-Filter nicht überall gleich zu sein scheint. Ich hatte zuvor einen variablen ND-Filter direkt bei K&F Concept auf der Webseite gekauft, und wollte nun über Amazon das exakt gleiche Produkt erwerben - war etwas Rätsel-Raten.Am Ende sind es aber denke ich die gleichen physischen Produkte gewesen.Zum ND-Filter selbst: solide Verarbeitung, funktional, tut was er soll, keine Beanstandung. Was will man mehr? :-)
