PolarPro Peter McKinnon Signature Edition II VND - Neutral density filter without vignetting. Ideal for shooting in bright conditions with large apertures. LOG format recordings are possible with an ISO setting above 400. The preset stop range prevents the possibility of cross-polarization. No vignetting occurs up to a focal length of 16 mm. The tactile feedback mechanism ensures easy handling. The built-in Defender360 filter protection provides a waterproof and dustproof seal. ND filters extend exposure time. A neutral density filter (ND filter) blocks a portion of incoming light. With a neutral density filter, you can significantly extend exposure time and achieve effects like blurred water or prevent overexposure of the image when shooting with an open aperture in the midday sun.
