Compatible with lenses with 67mm filter threads, this 2-in-1 True Color Variable ND2-ND32 & CPL Filter from Neewer combines a neutral density filter with a circular polarizer so you don't have to stop shooting to swap filters. Part of the brand's NW Series S, this filter offers precise, adjustable control from ND2 to ND32, reducing 1-5 stops of light to allow for the addition of blur and a sense of movement to an image. It is especially helpful when shooting under bright lighting conditions. Simultaneously, the circular polarizer component of this filter can reduce reflections and glare. Made from CNC-machined aluminum alloy, the nonslip top knurling of the frame makes it easy to install and remove the filter.
