One of the most important accessories for each lens you own 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.
The EW-88C Lens Hood is designed for the Canon EF 24-70mm f/2.8L II USM Lens
