Dedicated to the Canon RF 70-200mm f/4L IS USM lens, the ET-83G(WIII) Lens Hood helps to minimize flare by deflecting stray light from entering the lens. The hood also provides additional protection to the lens from accidental impacts, bumps, or scratching.
★★★★★ Perfect fit for my Canon RF 70-200mm f/4L and does a great job reducing flare. It also adds solid protection to the front of the lens without feeling bulky. Exactly what I expected from Canon.
