Per lavoro mi occupo di Fotografia e Video e grazie ad k&f concept ho potuto conoscere e testare questo favoloso Filtro Polarizzato Regolabile di K&F CONCEPT, marchio specializzato in produzione di accessori per Fotografi e Videomakers vincitore di innumerevoli premi Red Dot Design Award.

In questo caso ho testato il Filtro Polarizzato da 72 mm regolabile e devo dire che già dai primi istanti mi sono innamorato di questo Filtro!

Si intuisce già dalla confezione, che arriva in una elegante scatolina sigillata, a garanzia che il prodotto sia nuovo, contenente la custodia rigida del filtro, anch'essa dal design ricercato e in plastica rigida e robusta, ideale a proteggere il Filtro durante il trasporto.

Si apre a vite, girando il coperchio e al suo interno troveremo il nostro filtro, tenuto fermo grazie all'ingegnoso sistema di semicerchi in silicone.

Sul lato del Filtro troviamo ben scritte tutte le caratteristiche dello stesso, e una volta avvitato sul nostro obiettivo grazie alla filettatura che scorre alla perfezione, potremo regolare l'angolo di polarizzazione semplicemente andando a girare la ghiera dentata del filtro.

Come potete vedere dal breve test video il filtro riesce a bloccare il 100% della luce dello schermo, cosa che garantisce la perfetta polarizzazione della lente.

Non ho notato aberrazioni cromatiche, ne riflessi o distorsioni. Consiglio vivamente l'acquisto di questo Filtro che saprà ampliare le possibilità creative anche del Fotografo più esigente!

Good morning everyone.

K&F Concept products are of good quality.
Used to boat photos, this filter is very effective in reducing reflections on the water, you have to find the right angle of view and you will have good photos.
I've used it with a variety of lenses and never disappointed.
Delivered in a box equipped with silicone wedges to preserve the filter and prevent it from moving, great.

Friendship, Laurent

The product comes with quality packaging, taken care of externally while internally we find a plastic package to carry and store the filter itself.

(in the video you will find, unboxing, first impressions, tests and review) I will

not dwell on the technical specifications since they are already widely mentioned in the product description but, I will tell you about my user experience and impressions.
As soon as we open the package, we immediately find the filter in our hand, housed in its transport package.
It immediately shows that the filter is of excellent workmanship as far as the materials are concerned, the glass coating is easily visible because it tends to give a greenish reflection to the lens but, this reflection does not change the tonal range that we will have in the photo, but the filter tends to lose about a stop of light.
I immediately tested the product and it was highly efficient, first of all because it does not tend to create lens flare deriving from the presence of lights and headlights, secondly, the adjustable polarization manages to bring up to two good levels and also to cancel reflections on water and shiny objects.
The loss instead of detail is almost negligible.
The tests were carried out on a Sony A7M2 with a 50 F1.8 lens.

In conclusion, it is an excellent product that has a good quality/price ratio, my final rating is 5 stars

Despite software that allows a lot of things, a real polarizer is still essential to remove window reflections, make beautiful skies and photograph fish without reflections from the surface of the water.
The price of this model is astonishing, in terms of its quality.? Recommended purchase.

A polarizing filter that does exactly what it should. It arrives well packaged and the first test images are in order. The next photo tour will focus more intensively on the filter and adjust my review if necessary.

I ordered the 72mm diameter CPL filter.
It comes packaged in a small cardboard box, which contains a plastic storage case with filter.

The filter is quite thin, which reduces the risk of vignetting.

I use the filter on my Fuji 10-24 zoom to increase contrast or remove annoying reflections.
That works really well too.

I also like the good grip of the filter holder. This makes it easier to turn the filter.

Definitely happy with this purchase. No noticeable loss of quality in my pictures. Smooth transition when rotating the filter.

As far, I use to buy only Tiffen products but this one it is fantastic! It’s doing great job and saves a lot of time in post editing

Great quality at great price. No expert but better than some pricier options I tried.

This polarizing filter arrives neatly packaged in a case. I'm happy with it.
