This K9 Wolverine 100mm Slim Knight Magnetic Neutral Night, ND, and CPL Filter Kit from Kase is an ideal filter kit for long-exposure nightscapes and astral photography. It builds on the K9 filter holder by adding a rotating circular polarizer and a neutral night noise pollution filter. It also includes a trio of neutral density filters for added exposure control. Each of the ND filters is a square 100x100mm glass filter that has a slim 1.1mm thickness to minimize potential vignetting with wide-angle lenses. A 100x100mm UV filter is also included to reduce additional ambient ultraviolet haze.The K9 filter holder features dual filter slots, allowing more than one 100mm-wide, 1.1mm-thick filter to be used at a time for even greater image customization. The included adapter rings allow it to be used on lenses with 67mm, 72mm, 77mm, and 82mm filter threads. Additional adapter rings and step-up rings are compatible, and available separately.This kit is compatible with other holders and filters for 100mm wide, 1.1mm thick filters made by by Kase, Lee, Haida Pro, Haida M10, Formatt Hitech, Cokin Z, Nisi and more.None Drop-in magnetic circular polarizer filter for separately available Kase K9 100mm Filter HolderPolarizer filters help to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface, clear up haze in distant landscapes, and provide more saturated, vivid colorsDoes not disrupt auto exposure or focus features and is constructed from Schott B270 Superwhite glass for enhanced clarity and color fidelityMulti-coated to prevent internal ghosting and reflections and features scratch-resistant, mold-resistant, and hydrophobic coatings on each glass surface to protect the filter substrate and result in an improved beading effect when in contact with water or oil for greater cleaning efficiency2x filter factor reduces exposure by 1 stopDesigned to avoid vignetting when used with a wide-angle lens and can be independently rotated to adjust the intensity of the polarization effectPlastic case for storage and transport
