Designed to help minimize flare and ghosting by blocking stray light, the Canon ET-83FW III Lens Hood keeps light out by extending shading the end of the lens. This extension also provides additional protection against accidental impact to the front element of the lens.
Compatible with the following lenses:
Canon RF 70-200mm f/2.8L IS USM
Canon RF 100-500mm F4.5-7.1L IS USM
