As a landscape photographer, I found this filter system really interesting. Unlike screw filters, these filters are applied and removed in a fraction of a second, while unlike plate filters they are much less bulky, lighter and, of course, much quicker to install.

PACKAGING AND CARE OF DETAILS

The filters are delivered in a convenient and very well made case with four compartments. The case, in the back, has a hook and loop buckle that we can use to attach it to our tripod or our trousers and, in addition, a metal ring so that it can be attached to our backpack, tripod column or wherever we prefer. Finally, the zip closure of the case is resistant to rain or water infiltration.
The filters are contained and protected individually inside special sachets so as to avoid any potential damage.

CONSTRUCTION

These magnetic filters from the K&F Concept Nano Series are made of optical glass that is perfectly resistant to water, oil and dust. The external frame is in slightly knurled aluminum to allow an excellent grip.
They are extremely thin and, even by mounting all three filters at the same time (UV, CPL and ND1000), the thickness is extremely low.

UV FILTER

In the photographs I took with the UV filter there are no color alterations, no loss of sharpness and details and no dominants of any kind.

POLARIZING FILTER

This polarizing filter provides a pleasant overall contrast to the image, increases the contrast between individual colors and saturates them without overdoing it. In addition, it provides a very slight warm cast which, personally, I do not mind but which is easily corrected in post-production.
