The Canon ET-87 Lens Hood is designed specifically for the EF 70-200mm f/2.8L IS II USM to prevent unwanted stray light from entering the lens.
This petal-shaped ET-87 lens hood provides multiple functions:
- Shades the lens from stray light, improving your contrast and image quality
- Helps to keep moisture or wind-blown debris off the lens in inclement weather
- Protects the front barrel from the inevitable impacts against walls, door frames, and other real-life obstacles
