NiSi Filter kit for DJI Mavic Air (6 Pack) allows you to achieve more natural and refined videos and expands your creative possibilities. The ND filters lengthen the shutter speed by reducing the amount of light entering the camera - it gives a more natural sense of motion when filming.  Each filter is exceptionally light and features an ultra-thin frame.  Each filter is made from optical glass and features Nano Coating and a Waterproof Coating.  The ND's feature the same IR technology available in NiSi's Square filters to reduce color cast and allow a very true to life color.  The kit includes the following 6 filters: Natural Night, CPL (reduces light by 1.5 Stops), IR ND4 (2 Stop), IR ND8 (3 Stop), IR ND16 (4 Stop), IR ND32 (5 Stop).
