This is a 3-pack multi-coated optical glass filter kit designed for the DJI Osmo Action.
Includes the following filters:
ND16-CPL: A combined Neutral Density (ND16) and Circular Polariser filter to reduce light by 4 stops while eliminating glare and reflections.
ND64: A heavy Neutral Density filter that reduces light entering the lens by 6 stops, allowing for longer exposures or a wider aperture in bright conditions.
GND8S: A Graduated Neutral Density filter used to balance the exposure between a bright sky and a darker foreground.
