The Haida M10-II Circular Polarizer filter is a dedicated drop-in filter for the Haida M10 and M10-II 100mm Filter Holders. The innovative drop-in filter design of the M10 series filter holders allows the drop-in filter to be placed in a dedicated filter slot that creates a light tight seal while still allowing for the use of square and rectangular filters using the filter guides found on traditional filter holders. The M10-II Circular Polarizer filter helps remove reflections and glare from non-metallic surfaces, such as water and glass. The nano-multicoated CPL filter features anti-reflection and anti-color cast properties, and conveniently features an independent rotation wheel that allows you to adjust the polarization of the filter. The M10-II drop-in filter line is made from aerospace aluminum and feature an easy to use pinch-and-release grip design. M10-II drop-in filters are compatible with both the M10 and M10-II filter holders.
