The innovative new drop-in filter design of the M10 filter holder allows the M10 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.
This two in one filter features both a Circular Polarizer to help remove reflections and glare from non-metallic surfaces, and a solid Neutral Density filter to help capture longer exposures. The multicoated CPL + ND filter features anti-reflection and anti-color cast properties, and conveniently fits in the dedicated drop-in slot of the M10 filter holder with an independent rotation wheel that allows you to adjust the polarization of the filter.
