The Shutter Collection for the GoPro Hero cameras is part of PolarPro’s Cinema Series line. Featuring the highest-grade glass and coatings delivering pristine optics. Each of these filters directly replaces the front lens element on the HERO7 Black, HERO6 Black, and HERO5 Black Cameras, reducing the amount of glass you are shooting through. Included in this set are an ND8, ND16, and ND32 filter for reducing shutter speed to capture smooth cinematic videos. The Cinema Series Shutter Collection is designed to be perfectly compatible with the GoPro Karma Grip and the Karma drone. For cinematographers looking to drop shutter more than 5-stops, the Cinema Series Filters can be combined with the standard push on Karma Filters for even more light reduction.
