Dedicated hood for RF 800mm lens

The Canon ET-101 is a lens hood engineered specifically for the RF 800mm focal length. It attaches directly to the front of the compatible optic to block stray light from entering the barrel. Photographers shooting with this long telephoto lens use the hood to protect the front element and maintain contrast in bright conditions.

Petal shape limits vignetting at 800mm

The petal-style profile is cut to match the angle of view at 800mm, preventing the hood edges from appearing in the corners of the frame. A deeper circular hood would cause vignetting at this focal length, so the shaped design is the practical limit of the mounting interface. It cannot be used on lenses with a different diameter or angle of view.
