Airframe™ Construction: Polar Pro’s filter design specifically designed for aerial filming. The ultralight construction utilizes a precision threaded aircraft aluminum frame for smooth gimbal operation. Cinema Series™ Glass: Polar Pro’s filter collection using the highest end glass & coatings available for pilots who demand the best. Cinema Series glass has high light transmission & a lower refractive index. Filters Included: ND16 Filter (4.54g): The 4-stop ND filter is what we use on partly cloudy to mildly sunny days where we need to knock the shutter down by 4 stops to achieve a shutter of 1/60th. ND32 Filter (3.47g): The 5-Stop ND filter is what we use on extremely bright days. This filter is designed to take down the Phantom 4’s shutter speed by 5 stops. This is a very dark filter so it should only be used where there is enough available light to reduce. We use this shooting in the desert or over snow on very bright days. ND64 Filter (3.47g): The ND64 filter is designed to give you control of your shutter speed. The filter reduces shutter speed by 6 stops which is perfect for getting shutter to 1/60th or 1/50th on extremely bright days. The slower shutter speed means that you can capture epic, cinematic quality content even in the brightest conditions.
