The 77mm Peter McKinnon Mist Edition II VND ND64 to ND512 Filter from PolarPro is designed for lenses with 77mm front filter threads and provides an exposure reduction of 6 to 9 stops. The 1.8 to 2.7 density creates a darkening of the entire image, allowing a wider aperture or slower shutter speed than usually possible. The filter produces a dreamy, smooth, angelic look that provides an added layer of production value to your footage. Giving highlights a softer look, this filter excels at providing subjects with a polished appearance without sacrificing contrast and color accuracy. Ideal for creative shots in documentaries, short films, music videos, and other commercial projects.
