The i1 Series ND8/CP filter is a professional combination ND8 and circular polarizer filter for the DJI Inspire 1 camera.
The protective UV filter that comes standard on the Inspire 1 is screwed off and this filter is screwed on in it's place.
This neutral density filter reduces rolling shutter artifacts (e.g. jello) by slowing the shutter speed of the Inspire 1 camera while the circular polarizing qualities of the filter cut glare and increase the contrast between clouds and the sky.
The i1 Series ND8/CP filter is recommended for cloudy to moderate sunlight.
