Attaching a Lens Hood

When the dedicated EW-83H hood is attached to the EF24-105mm f/4L IS USM lens, it blocks stray light and protects the front of the lens from snow, rain, dust, etc. Before storing the lens in a bag, etc., you can attach the hood in reverse.

1 Align the red dots on the hood and lens edges.     2 Turn the hood as shown in the illustration. Turn the lens hood clockwise until it attaches securely.

• If the hood is not properly attached, it may obstruct the image’s periphery, making it look dark.

• When attaching or detaching the lens hood, grasp the base of the hood when turning it. Grasping the hood’s edges when turning it may deform the hood
