• The 255 plastic hood acts as a lens shade to reduce reflections off the filter’s surface. It clips directly on to the Cokin M (formerly P series) plastic filter holders. It is possible to stack multiple hoods to create a longer lens shade for telephoto lenses. The Cokin 255 hood attaches to outside of filter holder and doesn't impede graduated filters' movements.
