The Canon ET-87 Lens Hood is designed for use with the 70-200mm f/2.8L IS II USM Telephoto Zoom Lens. Lens hoods shade the front element of the lens from extraneous light and help to prevent flare.
★★★★★ Perfect fit for my 70-200mm f/2.8L IS II USM. It blocks stray light and flare effectively and feels like genuine Canon quality. A must-have for protecting the front element.
