DESCRIPTION
Dedicated to the Canon EF 70-200mm f/4L IS II USM lens, the ET-78B Lens Hood helps to minimize flare by deflecting stray light from entering the lens. The hood also provides additional protection to the lens from accidental impacts, bumps, or scratching. It is offered here as a spare or replacement for the hood originally included with the lens.
The addition of a lens hood can help prevent lens flare, the circles of light that can accompany images where a strong light source is just outside the frame. These types of lens flares occur when indirect light rays pass through the front lens elements but don't make it all the way through to the image sensor. Almost all EF and TS-E lenses have a Canon lens hood engineered specifically for it.
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 it protects the front barrel from the inevitable impacts against walls, door frames, and other real-life obstacles.
