The magnetic round filters from Kase are made of high quality KW glass, which is especially characterized by its color neutrality. You can therefore rely on your image quality. These filters are perfect for photographers who do not need a complete square system. The advantage is that they are lighter and more compact. Each set consists of an ND8 filter, an ND64 filter, a CPL, a magnetic adapter ring, a matching magnetic lens cap and a filter bag. These kits of our magnetic round filters are interesting for both photographers and filmmakers and allow you to control both reflections and light. Our magnetic round filter kits are available in diameters of 67mm, 72mm, 77mm, 82mm and 95mm.
