Canon EW-83H Lens Hood for EF 24-105mm f/4L IS USM Lens

Lens hoods are primarily designed to prevent unwanted stray light from entering by extending and shading the end of the lens, ensuring no problems with vignetting or motor functions.

Additionally, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact. The "petal" shape of this lens hood maximizes the amount of hood coverage for the minimum amount of weight and hood area. Lens hoods match the specific focal length of the lens it was designed for EF 24-105mm f/4L IS USM Lens.
