The Canon ET-78B Lens Hood is designed to fit the Canon EF 70-200mm f/4L IS II USM lens. It deflects stray light from entering the lens, which helps in minimizing flare. Additionally, the hood can be used to protect your lens from any accidental damage, such as impacts, bumps, or scratches. This item can be used as a spare, or as a replacement for the Canon ET-78B Lens Hood that is originally included with the lens.
