Cinema Series™ Glass: PolarPro’s filter collection using the highest end glass and coatings available for pilots who demand the best. Cinema Series glass has a high light transmission and a low refractive index.
Airframe™ Construction: PolarPro’s filter design specifically for aerial filming. Feather-light construction utilizes a precision threaded aircraft aluminum frame for smooth gimbal operation.
ND64 Filter (1.31g): This filter reduces the camera's shutter speed by 6 f-stops and also reduces glare. We use this filter most often when filming on bright sunny days when the native shutter-speed is reading 1/32000th, or for long exposure photography.
