Short product description:
K&F Concept hybrid 2-in-1 camera filter combines a circular polarizer (CPL) with a variable neutral density (ND) fader rated ND2–ND32 in a 67mm thread. It reduces reflections and glare, enhances color saturation via the CPL function, and offers adjustable light attenuation from 1 to 5 stops for longer exposures or wider apertures. Suited for landscape, architecture and motion-blur photography where both polarization and variable ND control are needed.
