- EF-S 18–135mm f/3.5–5.6 IS USM
One of the most important accessories for each lens you own.
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.
