The ET-77 Lens Hood from Canon helps to block sunlight or other light sources for the RF 85mm F/2 Macro IS STM lens to prevent glare and lens flare. The hood also provides additional protection to the lens from accidental impacts, bumps, or scratching.
★★★★★ Perfect fit for my RF 85mm F/2 Macro IS STM. It blocks glare effectively and adds great protection to the lens. Solid Canon quality and easy to attach.
