The Canon Lens Hood ET-87 Lens Hood, as with other lens hoods, is made to keep undesired side lighting from entering the lens. It does this by extending and shading the end of the lens. Furthermore, since the hood extends from the lens, it gives extra protection from accidental impact. It is removable and attachable in reverse to take up as little space as possible when storing in camera bag.
The Canon ET-87 lens hood is compatible with the Canon 70-200mm f/2.8L IS II USM Telephoto Zoom Lens.
