PolarPro Peter McKinnon Edition - 67mm Filter (6 to 9 Stop)

The PolarPro 67mm Peter McKinnon Edition Variable ND 6 to 9 Stop Filter features 1.8 to 2.7 density, thus darkens an entire image, and allows you to photograph with a wider aperture. You will be able to easily control the degree of density by rotating the front filter ring, which will help you predetermine the additional exposure length. You can also easily convey movement speed, and field depth control because of the filter’s ability to slow down exposure time and increase aperture. 

This filter is constructed from quartz glass for enhanced durability. To prevent internal ghosting and reflections, 16 layers of anti-reflection coatings offer scratch protection to the filter substrate while promoting clarity and color fidelity. The coatings associated with the PolarPro 67mm Peter McKinnon Edition Variable ND 1.8 to 2.7 Filter also result in an improved beading effect when in contact with water or oil, allowing for more efficient cleaning.

The quartz optics are set within an aluminum alloy filter ring assembly for durability while remaining lightweight. Both a filter case and pouch are included for storage and transport, as well as a slim cover. When used to grip the filter during installation, the cover helps to prevent fingerprints from being left on the filter's glass surfaces.
