Description:
A lens hood provides multiple functions: it shades the lens from stray
light, improving your contrast and image quality; in inclement
weather, it can assist in keeping moisture or wind-blown debris off
the lens; and it protects the front barrel from the inevitable impacts
against walls, door frames, and other real-life obstacles. Almost all
EF and TS-E lenses have a Canon lens hood engineered specifically
for it.
