SmallRig Attachable CPL Filter with M-Mount Adapter (67mm)

The Attachable CPL Filter with M-Mount Adapter from SmallRig helps eliminate reflections from water, glass, still objects, and more. This also helps improve image clarity, detail, and color saturation. The overall effect can be adjusted by rotating the filter. A CPL (Circular Polarizer) filter reduces the amount of available light by 1-2 stops and requires either the aperture or shutter to be opened as compensation, which makes it effective as a neutral density (ND) filter.
