There are different types of CPL filters on the market, with different quality, finish and of course price. For those who do not want to spend so much, the products of this brand may be for you thanks to the excellent quality/price ratio. Even in this new type of filter with the new technology, particles were included, the quality is really excellent both constructively and functionally. We will have a magnetic filter that is applied to a ring previously screwed to our lens, so we can then apply any magnetic filters that we have in our possession. This filter has a special feature compared to the previous filters: the nanoparticle technology is a coating that guarantees excellent water resistance, that is, the small water droplets slide much more easily on the glass and do not leave any marks that could leave stains or halos on the lens. The filter itself, like all filters of this type, works very well. By turning the filter clockwise or counterclockwise we will apply more or less this type of filter that reduces or in any case reduces reflections and lights, especially on reflective surfaces such as glass and water or even on the hair, light reflections are eliminated, creating a more homogeneous and less luminous hair. A good product to always have with you on different occasions where reflections can damage our photographic creations.
