This item provides a circular polariser as well as a neutral density filter (3 step) in one single construction reducing the need to carry two separate filters.
This item provides a circular polariser as well as a neutral density filter (3 step) in one single construction reducing the need to carry two separate filters. Circular polarisers can be used to reduce reflections from water and other non-metallic surfaces as well as to reduce haze and saturate colours. Neutral density filters allow reducing exposure by blocking light and thereby allow capturing motion within the frame.
