Canon EW-83H Lens Hood
The Canon EW-83H Lens Hood is a short, conical-shaped "tube" that attaches to the front of the Canon EF 24-105mm f/4L IS USM Lens to shield it from extraneous light. This inexpensive accessory is a must-have for your camera system, as it helps prevent lens flare, ghost images, loss of contrast and other unwanted light effects.
