Air 3 ND Filters Set (ND8/16/32/64)

The ND filters provide experienced users with precise control over shutter speed, allowing them to produce smooth footage in bright environments with lower shutter speeds. Flexible use of this set can ensure clean footage, even when the shutter opens to 180° with a low ISO*. \n \n* Shutter Opening Angle: A common way of describing the shutter speed relative to the frame rate. Exposure Time = Shutter Opening Angle/(Frame Rate × 360°). For example, if the camera is recording at 24fps with the shutter open at 180°, the exposure time is 1/48 s.
